Train the new modality no more than twice per week for at least four to six weeks (ideally with two to three days of rest between). This will give your connective tissue time to heal between sessions and increase load tolerance. (Remember, collagen synthesis levels within joints stay elevated for three full days postexercise.)128 You can then bump up the training frequency to three days per week for another four to six weeks. This rule applies whether you’re a couch potato or dedicated fitness junky.
