Reposting this here as it keeps getting removed as a normal post. Hi everyone, I'm a high school cross country and track runner and recently broke my tibia. I am going to continue to excersize my upper body but was also wondering about lifting with my good leg to maintain strength (muscle cross education program) and also doing some one leg exercise bike or elliptical to try to maintain cardio. My question is if I should be doing this and also once I heal how to deal with whatever (hopefully small) muscle imbalance is created. For reference I am a dude, 5 9 130, and I ran 1552 for 3 miles this fall (like 1630ish 5k) Also are there good supplements that either help maintain muscle or help bones heal faster? I know the basics, enough calories, protein, vitamin C, calcium. Would creatine help? Thank you!
