Can I use my elastic tubes to do what you do with flat Quantum Bands?

Honestly, in most cases, you could try, but tubular bands (which are molded) will not provide the versatility of that comes with continuous looped bands. Also with certain exercises, you are risking breakage because the tubular band does not have the durability to match the demands of the exercise. Therefore I do not recommend performing exercises demonstrated on, our Youtube Channel, Instagram Account, or any of our free training resources.
