Query: good book for senior citizensto read and act accordingly.

like the idea of less reps.. heaver weights seem to have more effect on building muscle where desired. our gym has different types of equipment so will have to adjust exercises accordingly.. book was good reading as it opened my eyes as to thinking wrong in regards to building heart and lung muscles. at 91 years of age still trying my best to stay vertical.
