The Rainbow Mini Loops are really versatile for full body. They come in different levels of resistance, starting with yellow, which is the lightest resistance, to purple, which is the strongest resistance.
You can use them for upper and/or lower body strengthening, like strengthening the hips and glutes. They are also really good for scapular shoulder blade stability work, since the different levels allow you to control the resistance better than other products.
