Rope Climb - 4 sets. Some of our kids can climb using no feet, while our heavier guys need an extra pair of feet to get to the top. Hammer Incline - one set must get at least 8 reps. Once they get 10 weight gets jacked up. Straight Bar Curls - by this time their grip is pretty fried.
Wrestling comes down to grip.
I think I smell smoke. This is a great exercise for core strength. We usually vary the reps but during the season we use higher reps with heavy weight to make the workout a little more metabolically challenging. Dips - 20 rep set. Concentrate on perfect form, one second pause on the top and bottom of the movement.
