108kg Speed is the nervous system’s ability to generate force through the muscles. Agility is either innate or trained; nonetheless, it requires a high level of proprioception—feeling your body and its position—so you can slow down, accelerate, change direction, and, most importantly, produce force from uncomfortable positions. All of this requires both targeted work and the “behind-the-scenes” work, based on converting between three types of muscle contractions: - Eccentric - Isometric - Concentric That’s why I’ve always felt greater benefits and enjoyment from athletic training in the broad sense, which demands: strength / speed / agility / endurance / explosiveness / change of direction. Now that I’ve returned to combat sports training, everything feels easier—and in general, whatever I start training now, it’s easier for me.
