If you have iOS, I highly recommend the Fitbod app. I've tried so many other apps and I just end up doing all this tedious logging that gets frustrating. But Fitbod just outsources all that away to its machine learning backend. It uses an algorithm to maximize your strength gains and uses the equipment you have at home (or the gym). So even if you only have a few pieces of equipment, it can still create a diverse workout for you. And it has videos for how to do each exercise, which comes in handy more than you might expect. I like it because I don't have to keep track of anything, don't have to do any work in terms of number crunching. It's like having a smart personal coach.
