Yes, that’s power training.
The bulk of the lean muscle mass we lose as we get older is type 2 fast twitch muscle fiber. Type 1 fiber is easier to maintain with resistance training, think “old man strength”.
But to maintain as much type 2 fibers for as long as possible requires power training. Olympic lifts, kettlebell ballistics, sprinting, etc.
Olympic lifts are way too technical (therefore risky) for some of us, including me. So kettlebell ballistics and sprinting are perfect.
