I am cautiously optimistic at this point. My nephew is a weight lifter and wanted to know how much I could bench press. It proved to be 150 lbs which he thought was good for my age (77) but seemed low to me. So I asked my trainer if we could try improving that. And this is so interesting. Three weeks in and we still are just working on lower intensities and a lot of push-ups but it's very slow, and I do think that I am actually gaining a little strength without hurting myself. My goal right now is just to get to 160 lbs.
