Working from a deficit complicates matters a bit. 10 sets of 5 and my shoulders were FRIED. I would say these are about 25-40% harder than the normal variety. It’s difficult to see but there are two 45# plates under each hand, adding about 8 inches of range to the HSPU.
I sometime have to force athletes to rest between sets. Often I’ll give them things to do to take their mind off the fact that they are actually resting for the next set. Today it was Prone Rope Pulls. Stabilize on one arm, lock the hips into place, and alternate pulling the rope with each arm. It’s easy to do it wrong. In fact, if it feels easy you are likely doing it wrong. Pay attention to the finer points of the exercise and very little weight is needed to produce an effect. Byron looks very solid here.
