I purchased resistance bands and Glute bands, they are fantastic quality and products at Shelter Fitness, and great customer service. Just an FYI, Glute bands can be used for so many different exercises than just glutes: ie., 1) Narrow close feet Squats, 2) place band around elbows for cable triceps pushdowns, yes lower the weight and keep elbows tucked in, also for overhead tri extensions, DB, Cable, Barbell, 3) band around elbows for DB or barbell back rows, experiment, sky's the limit with this product, don't follow other peoples routines, create your own, work the muscle, Shelter Fitness helps you get there faster and injury free!!!
