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.  They also are the perfect starter bands for a beginner doing the TA2 HIIT & Tabata Body Conditioning program.  

The Medium, Heavy, and X-Heavy bands can be used when more resistance is needed, such as squats, deadlifts and other lower body exercises.  They also work well for Crossfit athletes learning to do pull-ups anThe d muscle-ups, as well as strength athletes looking for Variable Resistance Training (VRT).  

“I’ve been training for 27 years now and in that time one of the single biggest mistakes I’ve seen people make is underestimating the effectiveness of resistance bands for losing weight, building muscle and increasing strength”.

    Great customer service

    I bought the TA2 Build bundle and absolutely love it! It's the only fitness program I've ever been able to stick with (I'm current in month 5). Shortly after I received my bands I noticed the Heavy band appeared to have a manufacturing defect. I sent a photo to customer service and in less than a week I had a replacement, no questions asked! It's a great product and company. I highly recommend.

    This bands changed the way I looked at resistance band training!

    I am able to workout anywhere I want in a small space when I'm traveling or can't get to gym and I'm sure you can build muscle with bands. The pump is amazing! Some days I prefer working out with bands instead of going to the gym even if I can get to the gym.

    Very impressed with the quality of these bands, i have tried som other bands i the past that were not very heavy duty but these ones are impressive. Looking forward to seeing some results in addition to strengthening back & core. PS James videos are very inspiring. Thanks
