      It’s been about a month since I started training with resistance bands for the first time after lifting weights for about two decades. At this point, because of these bands, I don’t see myself going back to the gym or even lifting weights again. The Undersun bands are well-made and this way of resistance training targets the muscles better than any machine or free weight I’ve used ever did. Also, I make it a point to watch and learn all of the online content and podcasts James Grage and the Undersun team offer when it comes to training. So far these bands have been a great investment and a lifesaver.

      Versatile, you won't regret purchasing

      Had to wait a while but after getting in touch with customer service, they were very helpful and responsive. Really glad purchased these resistance bands. I don't have space in my apartment to store a range of KBs and DBs so these are perfect especially right now. No excuse not to work out as they can go anywhere! You can feel the quality in the bands. The programme is easy to follow across the week and great if you are squeezed on time. No need for houra in the gym anymore. Lots of variation for muscles groups and range of resistance to suit you needs.

      Great product

      I needed something to take the place of my gym. I have been following the workouts and I am happy that I am able to continue with getting in shape. I do not know how long my gym will be closed, but I no longer need to worry.
