I started my summer soccer season about a month ago and it is affecting my working out very negatively. I have soccer 4 days a week, and it seems I just don't have the energy or intensity in the gym I had before the season started. I had been powerlifting 3-4 days a week before the season started but thought that would be too stressful on my body in season so I decided to do a full body workout 3 days a week (5 sets of each major muscle group)). But about every major lift (squat, deads, and bench) have significantly decreased in weight lifted. I have increased my protein intake to perhaps help repair my body since it is being used much more than before.
Does anyone have any suggestions on how to perhaps maintain my strength for after the season is finished or routines that have worked for you.
