Get More Fast Twitch: Less is More

Muscle fiber type is one of those topics on which people love to make uninformed statements. You may have heard things like, “Heavy weights work those slow twitch fibers.” Or […]

Squat Depth

In the discussion on transfer of training, squat depth is a hotly contested issue with many opinions clouding the view. On one side many people testify to superior strength and […]

Biarticulate Muscles and Synergy

When looking at muscle function, people often look at one joint, consider the muscles that act on that joint, and identify the muscles that perform opposite actions as antagonists to […]

Speed Science

This is a video series on top speed. The videos will cover physics, biomechanics, sprinting technique, and training strategies. The first video covers the physics of top speed and the […]

Strength Training for Speed and Vertical Jump

There is a lot of disagreement on the role that strength training plays in athletic development. Some say squatting is the only thing you need to do to increase your […]

Jumper’s Knee

Jumper’s knee is a term given to pain in the quadriceps or patellar tendon, the prominent tendon on the front of the knee joint which connects the quadriceps muscle group […]

Jump Science University: Muscle Tension

The video series below covers biomechanical and physiological factors that influence muscle tension. Along the way you get a good amount of university level anatomy and physiology education. With this […]

Achilles Strength (Bosch is wrong)

In a popular athletic development book, the author, Frans Bosch, cites force measurements in the achilles tendon of 3-6 x body weight (BW) in sprinting and 8-10 x BW in […]

Long Jump Case Study

In the athletic development field coaches often share general philosophies, models, ideas, etc. Someone might talk about things they consider when making decisions, but not share any actual data or […]

The Bilateral Deficit and Unilateral Training

What the heck is the bilateral deficit? Watch the video.

There may be some skepticism or confusion regarding the bilateral deficit. People may wonder why they cannot 1-arm bench press more […]

How to Get Eccentric Strength

Does lowering the weight slowly focus on eccentric strength?

First, does specific eccentric strength even exist? We classify muscle contractions as eccentric, isometric, and concentric. But physiologically is there any difference? […]

Front Squats vs Back Squats

Among athletes and strength coaches there is much debate over which is better for athletes who need to get stronger, front squats or back squats. This debate is rather silly. […]

The Strength-Speed Spectrum

Human movement relies on contraction of muscle-tendon complexes. Different movements require different types of contractions, which rely on different combinations of strength, explosiveness, springiness, and flexibility. The last three factors […]

Short vs Tall Athletes

Some of my first training experience was helping my friend Chris to jump higher. Over two years of training (with some breaks) he made great progress, despite not being a […]
