30 years ago I bought a cheapo weight set with two dumbbells and a bar bell along with about 80lbs in plates. Used it sparingly over the years mainly to help with back pain. Last summer I found a set of 40lbs dumbbells on craigslist and bought them. Also found 40lbs in plates. Now I have a nice set up to do maintenance on the upper body. Walking and riding keep the lower body in check. No need to do all the other stuff to maintain fitness, however since this stuff is hobby stuff, some folks like finding different ways to accomplish their goals.
