Online training client isaiahrivera1 is progressing back to full effort jumps. Having a 45+” approach jump is very stressful on the knees, and typically getting to that level involves training very intensely over periods of time that may result in connective tissue injuries. To get back to full capacity, Isaiah has been progressing training very systematically and using the numeric pain scale. #athleticlabonline #jumppro #jumptraining #boxjuml
