I have a Bodylastics set of bands; they're pretty good. I also picked up this band strength training program called the X3 Bar. I had seen ads on Facebook and IG, and at first I was very skeptical, especially at the price point. I had hurt my shoulder using my Powerblock dumbbells, and hadn't touched them in a while. So on a whim I said "screw it", and sold the Powerblocks on Craigslist. With that money I bought the X3. I've been pleasantly surprised. The creator claims that you won't need a gym membership after purchasing it, and some other customers have said that they've given up their gym memberships. But I use mine along with going to the gym.
