Ground-based free weight lifts, especially the explosive Olympic-style lifts, are highly recommended for athletic conditioning for the core muscles. They can provide a moderately unstable stimulus to augment activation of the core and limb muscles, while still providing maximal or near maximal strength, velocity, and power output.

This Kinetic Select from Developing the Core reviews the effects of muscle activity when performing exercises on unstable surfaces.

Bone tissue is “alive” and is a dynamic tissue that can respond to resistance training. In addition to the obvious effects of resistance training on muscle mass and strength, resistance training may lead to decreased risk for osteoporosis, fractures, and falls in later life.

Acceleration and maximum speed are terms used in speed development programs, and when developing a program, it is vital to differentiate between the two. This allows coaches to target their training to the capacity most important in their own sport.

For many coaches, there comes a point when coaching can become less about proving yourself and more about serving others. Loren Landow, Director of Football Performance at the University of Notre Dame, shares how that shift informs his approach to training, hiring, and leading in elite football. Landow distinguishes workouts from training; every block has a targeted goal, and every off-season is a chance to build brotherhood, uphold standards, and compete in everything they do. Landow also reflects on his path from cardiopulmonary rehabilitation to the private sector, the National Football League (NFL), and the University of Notre Dame. For him, when you can “weather the storm,” no career step is wasted. On the technical side, he argues that movement is his largest key performance indicator (KPI). Landow explains that deceleration is trainable, and athletes need movement literacy before reactive work. Listen to help solidify your standards, coach movement with intent, and adapt a service-first lens to last in the profession.
