I'm training around a jacked up shoulder (labrum tear), my main goal is to get in shape for winter sports. Just finished week 4 of the planned sets, distance, and rests from the Prowler Challenge, using a sled with a high shoulder harness. Conditioning is definitely improving, kinda cool, my resting heart rate is down from 73 to 65 (via Fitbit).
In the prowler challenge, with the heavier weights, did you "sprint" each set, moving as fast as possible, or more, "just keep it moving" to get all the work in?
You mentioned hill sprints as an alternative you considered in the book. If you had done a program where the conditioning was all lower body, would you have considered a little more pressing volume?
My legs are growing faster than they have in years. I am eating to keep up with the sled work, wondering if I am missing an opportunity, since I my arms are not involved in the conditioning. In the book, "You are welcome to push the upper body lifts as you see fit." Would adding FSL or Jokers to the upper body lifts be stupid? Would increasing the assistance volume for delts and tri's be better or worse choice?
