Resistance bands are often thought of as a home-workout compromise for people without gym access, but they add real, distinct value even in a fully equipped gym.
Variable resistance changes the muscle demand
Bands get harder to stretch the further they're pulled, which creates a different strength curve than free weights — useful for targeting the end range of a movement specifically.
They're ideal for activation work before heavier lifts
Light band work targeting glutes or shoulders before a heavier session is a common, low-cost way to 'wake up' a muscle group before it's asked to do real work.
