Real world anecdote: I recently discussed with a friend getting them some exercise equipment as a gift; at first we were targeting specifically "training that might help with keyboard RSI," but I soon realized that the biomechanics of RSI meant that a really comprehensive solution would have to involve exploring all over the body and figuring out where the real weak points are and training those, not just "around the wrist" - so grip trainer type equipment wouldn't be sufficient. It would have to be seen as an "overall fitness" type of problem. This led me, of course, towards free weights and a training program of general experimentation. But a small free weight set in the home can be a frustrating experience with no space or supporting equipment like benches and racks, plus the chore of reloading dumbbells with light weight constantly. My friend was rightly concerned about whether it would work out for her. So I reconsidered and landed on resistance bands. They're kind of unfashionable now - and for certain things having barbells and dumbbells and plates would be a lot better. But they store and transport easily, have essentially zero setup time, and there's plenty of exercises for them, many of which are straight-up adaptations of free weight movements. The more expensive Bodylastics set that I ended up buying, which was still only $70, allows for an enormous amount of resistance too. After doing that shopping, I kind of want to get some for myself too. My friend probably would have been lost at the first step because it's not like anyone marketing fitness actually tells you what you really need to begin addressing a problem. Neither will they explore whether the thing you buy is going to fit into your lifestyle. It's pretty gratifying to realize that some cheap rubber is best for the job.
