Weight training, even at low to moderate intensity or with lighter weights, can contribute to hypertrophy of collagen in tendons and ligaments.

“You can also weight train and have some benefit even at a low to moderate intensity. If you think about weight training where you have-- and it's not necessarily related to the incidence of DOMS, which is Delayed Onset Muscle soreness. But if you weight train lazy or easy from time to time-- obviously, you want to weight train very heavy from time to time as well because of more lean body mass growth. But if you weight train lighter, you're going to be able to do it more often, and it can still help with the hypertrophy of collagen-- for example, in tendons and ligaments.”
