Let’s look at the goal of building muscle, specifically. What your body responds to is tension or resistance. And there is a myriad of ways to get that effect. For example, curl a giant rock - this creates resistance. Or sit on a bicep machine in a gym - that’s resistance too. Free weights, resistance bands, machines - they are all tools that create mechanical tension to build muscle.
UNDERSUN Strength Bands create a very unique kind of tension called VRT, or Variable Resistance Training. VRT more closely matches the natural strength curve of your muscles than weights, which means better muscular contractions and therefore more muscle-building benefits.

Choose 1 of 5 different resistance levels.The X-Light and Light bands are great for upper body exercises that require a lighter resistance, as well as for shoulder mobility and strengthening programs.
The Medium, Heavy, and X-Heavy bands can be used when more resistance is needed, such as squats, deadlifts and other lower body exercises.
