The purpose of this article is to discuss the gray area that should be considered when it comes to implementing weightlifting exercises.

This article discusses the effects of instability on force and velocity throughout the body.

This article details the proper pick up, or deadlift, technique for the older adult, including progressions of three exercises that can aid in their ability to perform them properly.

Most law enforcement officers are physically taxed, mentally exhausted, and emotionally overwhelmed. As such, a complexity exists with a requirement to match the need for physical fitness in a demographic that lives their lives in a potential state of general exhaustion.

This purpose of this article is to supply personal trainers with resistance training techniques, progressions, and cues that can assist their clients in overcoming sarcopenia and to eventually press to the overhead position pain free and with confidence.

This article describes proper technique for the one-arm dumbbell snatch, which is a total body power exercise.

The path to the top is not always linear. For Jill Costanza, it included returning to school and stops in collegiate and military performance before becoming Director of Sport Science and Assistant Strength and Conditioning Coach with the National Football League (NFL) Detroit Lions. Costanza describes today’s sport science landscape as a “Wild West,” where definitions differ by perspective. Her focus centers on assessing the athlete and program effectiveness against the demands of the game to identify holistic interventions. She outlines how intentional systems, a clear communication funnel, and data visualizations help athletes and stakeholders understand the “why,” build buy-in, and tap into competitiveness. Addressing common misconceptions, Costanza clarifies that elite athletes can still have foundational qualities that need rewiring. She emphasizes movement quality, proprioception, and breathing while adapting for individual needs and neurological fatigue.
