The squat is one of the most widely used exercises in resistance training programs. The aim of this narrative review was to analyze the effect of the squat on lower-limb muscle hypertrophy. Briefly, the available literature indicates that the squat is an effective exercise for inducing hypertrophy of the quadriceps, mainly the vastii, but also the rectus femoris, although to a reduced magnitude. Multiple lines of evidence suggest little to no hamstring hypertrophy from the back squat. Although the gluteus maximus clearly participates mechanically in the back squat, few longitudinal studies exist on the topic. The limited evidence available on this topic suggests deeper squats may be more hypertrophic for the gluteus maximus, and that, squat depth beyond 908 of knee flexion may not provide further hypertrophy of the knee extensors. Despite the popularity of the many squat variations, there are still controversies surrounding their hypertrophic potential for lower-limb musculature. Further studies are needed to investigate the hypertrophic effects of different squat variations, as well as differences in hypertrophy because of squat depth, stance, barbell position, and different squat apparatuses/machines.

In order to ensure consistent and accurate results, coaches must take certain steps to ensure proper data collection. It is also important to establish sound protocols prior to testing.

This article applies LTAD principles to guide the process of generating an athletic profile (part 1) and sample program design (part 2) for a middle school athlete and a high school athlete.

Approximately 2 million youth from 6 - 12 years of age participate in football every year. This article discusses the importance of long-term athletic development (LTAD) for youth football athletes and the significance of a player development pathway for long-term success and longevity in the sport.

This article provides a few key tips on how to perform the deadlift more efficiently and safely. Some helpful coaching cues—such as keeping the head slightly up, activating the lats, and pushing the knees out—can assist a tactical athlete in executing the deadlift while increasing strength over time.
