Overindulging Endurance Runs
Too many long runs
Pounding the pavement is great for your heart, but doing too much can tighten muscles and decrease the flexibility you need to lift properly.
Sprinting taps into the same energy systems (ATP and glycogen) used in weight lifting and will help build the explosiveness needed for lifting. Bergeron recommends mixing eight 200-meter sprints with a 1-minute rest between efforts into your running routine.
