Basebody Long Fabric Resistance Bands Set of 3, Heavy Duty Stretch Elastic Bands with 3 Resistance Levels, Cloth Loop Resistance Bands for Full Body Workout, Pull Up Assistance, Resistance Training, Physio Therapy, Home workouts, Yoga, Pilates.

Exercises both upper and lower body but i went to a physio for expert training on these first or you could get that advice from the gym.

If I could give less than 1 star I would, they are terrible and offer no resistance at all, there is also no difference between any of them at all. They are absolutely useless

Hasn't help at doing pull-ups at all. I have sent them back as I couldn't used them for assisted pull-ups.
