I am curious to know that connective tissue you are referring to?
Connective tissue is not limited to ligaments and tendons.
Too, as fitness professionals, we re not in a position to know the health of an individual’s connective tissues. We make the assumption that their connective tissue is healthy. We have no idea if some has some form of tendinopathy or whether certain ligaments are on the verge of rupture due to overuse.
In a healthy body exercises such as yoga and pilates among others can have a positive impact on connective tissue but the benefits are relative to the health of the connective tissue of the individual.
