Powerful and thick thighs require gut-busting exercises like squats and leg presses. However, once you have acquired adequate thigh mass and strength, you should consider adding some balance and sharpness to the muscle bellies in your thighs. Although tough to accomplish, leg extensions provide a great way to carve the separations between the muscle bellies, and to accentuate the “teardrop” shape of the four quadriceps muscles of the anterior thigh.

Active Muscles in Leg Extensions

The three vasti muscles comprise most of the anterior thigh.1 The vastus medialis covers the medial (inner) part of the femur bone (thigh bone). When it is well developed, it forms a teardrop-like shape over the medial side of the knee joint. The vastus lateralis muscle attaches to the lateral (outer) part of the femur bone. The vastus intermedius connects to the femur bone between the vastus lateralis and the vastus medialis muscles. The fibers of all three vasti muscles come together at the quadriceps tendon, which crosses the patella (kneecap) to attach to the tibia bone just below the knee.1

Together, the three vasti muscles extend the leg at the knee joint, although the vastus intermedius may be more fatigue resistant than the vastus lateralis.2 The vastus medialis oblique (VMO), which is a small part of the vastus medialis muscle, attaches to the medial part of the patella. It is thought to help the patella track properly during movement of the knee. Improper tracking can increase the likelihood for knee injury.

The vastus medialis and especially the VMO part of this muscle are primarily responsible for tibial rotation (rotation of the tibia bone of the lower leg on the femur) during knee extension. This rotation or “twist” has been shown to increase the activation of the VMO portion of the vastus lateralis even more than doing knee extensions with the hip adducted (thigh rotated so that the medial portion of the knee is facing mostly upwards).3 Dorsiflexion of the foot (moving the ankles so the toes are pointing towards your head) also increases the activation of the VMO by more than 20 percent.4 Likely this is because the dorsiflexor muscles stabilize the tibia during knee flexion and resist rotation of the tibia on the femur as the knee straightens.

The fourth muscle of the quadriceps group is the rectus femoris muscle. It attaches to the anterior part of the hip bone just above the hip joint.1 The largest bulk of the muscle fibers are located on the upper three-quarters of the thigh, whereas the largest belly of the vastus medialis and vastus lateralis are more inferior (i.e., closer to the knee). The distal end of the rectus femoris muscle becomes tendinous and it creates a deep valley between the lateral and medial vastus muscles as it approaches the knee.1 It assists the other quadriceps muscles by extending the leg at the knee joint, although it is less effective when the hip is flexed than if it is straight.

Leg Extensions

The three vastus muscles of the anterior thigh are strongly activated by single-leg knee extensions. The rectus femoris is not activated as strongly, but it does undergo some overload when the anterior thigh is under contractile effort, about halfway up to the top of each repetition.

1. You should always warm up your knees with some stationary cycling prior to getting into leg extensions. Furthermore, the resistance on your first set should be fairly light to allow the joint to fully warm up before you get to the heavier stuff.

2. Adjust the knee extension machine so that the pivot point of the lifting arm is directly adjacent to the center of the side of your knee joint.

3. Position the ankle roller/leg pad over the lower part of the leg (above the ankle joint).

4. Take about three seconds to slowly extend (straighten) both leg so that the weight is lifted upward from the stack.

5. Continue upwards until the tibia and the femur bones form a straight line and the knee angle is straight. Hold this for two seconds at the top.

6. Slowly lower the weight (about four seconds down) towards the starting position. Once the knee has reached 90 degrees, start the upwards extension phase again. Continue for 12-15 repetitions for the first set. Lower the number of repetitions but increase the resistance for subsequent sets.

7. On the next sets, lift the weight upwards until the knee joint becomes almost straight, but just slightly short of a total knee lockout. Be careful that you do not “jam” the knee joint into a fully locked out position, because this could cause knee cartilage damage5, especially with heavy weights. Hold the top position for a count of three before lowering the weight.

8. Lower the weight slowly (four to five seconds) towards the starting position where your knee is flexed to 90 degrees. Just before the weight stack contacts the remaining plates at the bottom, start lifting it upward for the next repetition.

The downward movement should be slower than the upward phase because you are resisting the pull of gravity. The slow lowering of the weight stretches the muscle under a resistance and this is a great stimulus to improve muscle shape and size.6

Make sure that you do not hold your breath during the lift upwards.7 Rather take a breath at the bottom (start) of the lift, and exhale as you extend the knees/legs. Take another breath at the top and slowly exhale as the weight is lowered. Take another breath at the bottom and repeat the sequence.

This is a mechanically simply exercise, but it really can be very challenging and blood depriving8,9, especially if you try to control the weight as it is moving up and down. However, if you are willing to work through some discomfort, you will be soon enjoying your new shape and slabs of carved thighs.

Failures in Business: The Unseen Stepping Stones to Success

Equally significant is the need for businesses to remain vigilant about broader shifts in both domestic and global markets. Macro factors, whether they’re economic trends, geopolitical events, or emerging global challenges, can have profound ripple effects, impacting even the most niche industries. By staying abreast of these larger market dynamics, businesses can better anticipate risks, adapt to challenges, and capitalize on new opportunities. In an ever-globalizing world, the ability to navigate both the nuances of one’s immediate market and the broader global shifts is what separates thriving enterprises from those that falter.

TACTICAL Takeaway: Stay sharp and monitor your industry’s trends. When things shift, being ahead in understanding consumer habits offers you the flexibility to adjust and succeed. Things can change rapidly and the sooner you have insight into consumer behavior changes, the more opportunities you have to pivot.

Get Comfortable Being Uncomfortable

The sports nutrition industry is an interesting, fast-paced vertical where what’s old can quickly become new again but also what worked yesterday likely won’t work tomorrow.

It might seem counterintuitive, but it’s spot-on. Take creatine as an example. It hit the shelves in the early 1990s and quickly became a hit. Yet, a decade later, its demand had waned. Jump another decade to today, and it’s back more popular than ever.

TACTICAL Takeaway: The key for businesses is knowing when to go all-in on a product and when to ease off, as it’s the ever-changing consumer market that truly drives demand.

Never Rest On Your Laurels

Just because something “has always worked” doesn’t mean it’s going to continue to work (or continue to work as efficiently).

In the dynamic world of business, the saying “never rest on your laurels” holds more truth than ever. What propelled a company to success yesterday might not necessarily be the formula for its tomorrow’s success. Market demands, technological innovations, and consumer preferences are in a perpetual state of evolution. While a particular strategy or product might have been a game-changer at one point, there’s no guarantee that it will remain relevant or effective in the future. This inherent unpredictability underscores the need for adaptability and forward-thinking in any business endeavor.

This reality pushes companies to be proactive, always forecasting and adjusting to the next potential shift. Relying solely on past successes can lull businesses into complacency, risking obsolescence in the face of changing tides.

TACTICAL Takeaway: To remain competitive and relevant, businesses need to cultivate a culture of continuous learning, innovation, and agility. In essence, the past can inform and guide, but it’s the vision and readiness for the future that will determine enduring success.

Embracing The Journey

To any entrepreneur reading this: the road to success is rarely a straight one. At times, it may seem like every decision leads to a dead end. But remember, every misstep is an opportunity to learn, grow, and pivot.

The trials you face in business are not meant to discourage you. Instead, they are meant to shape you, refine your vision, and improve your strategy. As the age-old adage goes, “smooth seas do not make skillful sailors.” It’s the challenges that will arm you with the experience and resilience necessary for long-term success.

So, the next time you face a setback, remember that your next big success could be just around the corner. Embrace failure as a part of the process, learn from your mistakes, and continue pushing forward with a renewed sense of purpose and determination.

Lastly, don’t forget to enjoy the journey. With so much time spent working and navigating challenges, it’s essential to find joy and have fun along the way.

Negativity Is a Losing Mindset

By Marc Lobliner

CMO Tigerfitness.com

‘A good coach can change a game. A great coach can change a life.’

I coach my son’s U11 football team. I am just the line coach, but the dudes who coach with me are also in the same mindset as I am.

Positivity wins.

Let’s start off with last weekend’s game.

It’s 0-0, the opening kickoff is a short one and we fall on it.

You can hear our coaches getting our kids fired up and getting the offense ready for play. POSITIVE statements. A lot of “Let’s Go!” and energy.

On the other sideline, you hear the coaches angrily yelling at their players for the execution of the kick.

First play from scrimmage, our line makes every block and opens the outside for our running back to score.

You hear their coaches furiously yelling as we celebrate.

We celebrated and our fullback punched in the extra point.

After the kickoff, our defense held them to four and out. We got the ball again, touchdown. Extra point good.

14-0 in two offensive plays.s

Their coaches were still mad. Angry. Yelling.

We smiled, encouraged our kids, and ended up with a 42-0 mercy-rule win.

Our players are awesome, but not the biggest, not the fastest, not the strongest.

It’s all about culture and what you’re playing for.

We demand a lot of our athletes. Learn your plays, DO YOUR JOB, and we will win.

Every Tuesday after we win, I buy my linemen doughnuts and give them to everyone, telling them that a random lineman (changes weekly) said everyone deserves doughnuts. We don’t punish every mistake with extra running and up-downs. We focus on what we do RIGHT, and not what we do wrong.

The other game one of my linemen got called for a hold. He came off the field expecting to be scolded. I put my arm around him and said, “What happened?” He explained it and then I said, “You’re better than that guy, you don’t need to hold. Show the world how dominant you are!” He didn’t get one call the rest of the game and crushed it.

This is also my management style at work. Managers are usually garbage. You can do 1,000 things right and you mess up once and your manager attacks you.

THIS IS NOT THE WAY TO MANAGE!

Employees typically respond better to positivity, and numerous studies have found that positive reinforcement and a positive work environment can significantly improve employee motivation, performance, and well-being. Here are some reasons why, supported by various studies:

Increased Productivity: According to a study conducted by the University of Warwick, happiness led to a 12% spike in productivity, while unhappy workers were 10% less productive. The research shows that human happiness has large and positive causal effects on productivity.

Better Decision-Making Abilities: Research from the University of Pennsylvania’s Positive Psychology Center found that individuals who were induced to feel positive emotions were better at problem-solving and making decisions than those in a neutral state.

Boosts Creativity: Positive emotions widen attention and allow people to think more broadly and openly. This is discussed in the “broaden-and-build theory” by Barbara Fredrickson, which suggests that positive emotions broaden an individual’s momentary thought-action repertoires.

Enhanced Team Collaboration: A study from MIT’s Human Dynamics Laboratory found that teams that communicate effectively, with members actively reaching out and connecting with all other team members, were more successful. Positive interactions contribute to this dynamic.

Reduced Employee Turnover: According to the Society for Human Resource Management (SHRM), a positive work environment and culture encourages employees to stay longer in their jobs, thus reducing turnover rates. This is KEY at Tigerfitness.com where our staff has mostly been there for 5+ years!

Better Health & Well-being: A study published in the Journal of Applied Psychology found that positive work environments and low job stress are linked to better health outcomes for employees, which in turn can lead to reduced absenteeism and increased productivity.

Increased Engagement: According to Gallup, workers who are engaged and have high well-being are more likely to be attached to their organizations and are more productive.

Enhanced Learning & Flexibility: Research in the field of positive psychology has shown that positive emotions can facilitate adaptive thinking and flexibility in cognitive processing. This helps employees adapt to new situations and learn more effectively.

Higher Levels of Satisfaction: A study by BrightHR found that happiness is a key indicator of job satisfaction. Happy employees are more likely to report high levels of satisfaction with their jobs than those who report low levels of happiness.

Creates a Positive Feedback Loop: A study published in The Journal of Positive Psychology found that experiencing positive emotions leads to higher levels of resilience, which in turn leads to increased positive emotions. This positive feedback loop has a myriad of beneficial effects in the workplace.

How about parenting?

Same thing. PRAISE YOUR CHILD! Make sure they know you love them. While bad behavior should be addressed, be sure to also reward good behavior. Kid had a good day at school? Get him ice cream! Tell him you love him. Say you’re proud of him.

As my mother said, “You catch more flies with honey than with crap.”

And one can’t deny the lifelong impact of a good coach. As the sign in the office says, “A good coach can change a game. A great coach can change a life.”

Be positive and be a winner!
