Use these five resistance band deals to build muscle without weights for under $20

You don't need a set of weights to build muscle. Resistance bands are more affordable, easier to store and arguably just as versatile; you can use them for everything from strength workouts to stretches to yoga classes. 

Many of the best resistance bands come in sets of varying thicknesses — thicker bands provide more resistance — so you can use different bands to suit different exercises, or pick up a thinner one if you're doing a more gentle stretch rather than banded biceps curls. 

Although they are generally lower-cost than weights, Prime Day offered the chance to save even more using some significant resistance band deals. And, though the annual sales even is now officially over, many deals remain. 

We've used our experience testing resistance bands to round up five of the best resistance band deals on Amazon to help you build muscle, develop strength, improve your flexibility and deepen yoga and Pilates stretches without breaking the bank.

Although there are plenty of great weights deals around, you may not be looking for a set of dumbbells or a new kettlebell. Adjustable dumbbells combine several in one, but you still need space to store them. 

However, resistance bands are a more affordable and easy to store alternative to weights, helping add some resistance to bodyweight exercises like squats and lunges, or you can use them to ease into yoga stretches as well. 

That said, after reading up on resistance bands vs weights, you may decide that you'd rather have a mix of equipment. If that's the case, check out this excellent anti-Prime Day $30 adjustable kettlebell deal at Best Buy.
