Training Techniques for Optimal Muscle Gain and Fat Loss

Learn how to recognize and treat muscle dysmorphia in your athletes. In this session from the NSCA’s 2017 Personal Trainers Conference, James Leone covers many facets of athlete muscle dysmorphia, including the clinical features, identifying at-risk populations, using assessment tools, managing athletes suspected of having muscle dysmorphia, and how to treat it using a team-based approach.

There is a sound theoretical rationale supporting a potential role for muscle damages in the hypertrophic response, but a cause-effect relationship directly linking these gains to muscle damage is yet to be established. If such a relationship does in fact exist, it is not clear as to what extent of damage is optimal for inducing maximum muscle growth.

Few strength coaches have shaped sport performance like Al Vermeil — the only strength coach to earn championship rings in both the National Football League (NFL) and National Basketball Association (NBA). In this Gatorade Performance Partner Special Episode, Vermeil shares how a career built on explosiveness, adaptability, and relentless curiosity has transformed teams at every level. From advancing plyometrics and Olympic lifts in the 1970s to creating the performance pyramid and the innovative “time machine” testing system, his methods have influenced generations of coaches and athletes worldwide. Known for blending timeless principles with fresh, actionable ideas, he explains how mechanics, group management, and collaboration create consistent results and lasting trust. Along the way, Vermeil offers rare perspectives on coaching longevity, revealing how his adaptability and curiosity have kept him learning — and lifting — into his 80s. Gain practical insights to keep explosiveness central, integrate performance science, and strengthen your long-term coaching impact.

Building a Model of Multi-Directional Speed

Isolated muscle training methods do not necessarily transfer to better sports performance, because technique as well as strength contributes to successful performance. Resistance training for dynamic sports must involve ground-based movements that incorporate the coordinated stabilizing and dynamic functions of multiple muscles.
