Not necessarily. It's more about the movement in my opinion. Boxing isn't a static sport, so lifting should be static. Neither is it a steady-state sport so we should be strength training specific to the sport.

WHen you say don lift for bulk is it just the simple "lower weight more reps"?

What are the best workouts that work the fast twitch muscles?
