For example, my restorative class is all gentle stretch with focus on slow, rhythmic, breath. Even the stretches are supported by blocks and bolsters so it’s more releasing into a person’s existing range of motion than increasing their flexibility.
My BUTI yoga class, on the flip side of the coin, includes lifting our bodyweight in several planes of motion, so depending on the strength of the participant, that could be strength and / or endurance. Lots of balance. Some power in jump-forwards and jump-backs.
