I only use bands and calisthenics for a while now. I like bands, because it is really easy to get your workouts in, since you don't need to go to the gym.
I work from home so I usually exercise during my work hours lol.
The ones in the pic are the cheaper, molded ones, if you want something with more resistance you can get layered bands, but they are more expensive.
The max that I ever did with bands is a deadlift with a 300 and 400 pound band, but that obviously isnt the same as would be with weights. Haven't been to the gym so I cant compare at where I am in free weights.
