    This program has been a game changer!

    James Grage has completely changed the way I work out, I am so grageful (that was on purpose, haha) I found his tutorials on Youtube. I had no idea how to work out with bands and then I found James program, he teaches and explains things so well. I have been using bands now for about 6 months and I will never go back. Some of the benefits I have experienced is that I have had just as good if not better workouts. I like how James explains that our muscles don't know the difference between weights and bands, all they know is resistance and bands have given me a better workout. Also, bands have allowed me to stay away from injuries, there is a lot less pressure on my lower back and I have been able to maintain a consistent workout schedule because I am not hampered by injuries from the gym. Another benefit for me is that I can work out at home and I have incorporated my kids into my routine, they work out with me regularly and it has been a fun family experience. I have been preaching the gospel of bands since I started and I am just really appreciative of James and Annik. James also strikes me as a really nice, down to earth guy. I would really like to meet him one day. Keep up the good work James!

    It was excellent!! I get the same feeling as if I'm working out at the gym . It's convenient , get to workout at home and take them with me when wherever I go. As a first responder being in good shape and having a healthy lifestyle is very important. Undersun has really help me get my workout before or after work and I don't have to worry about getting injured and not being able to perform my daily task.. this is one of the best investment ever. I hope to see more workouts programs with the bands in the future.

    Anytime Anywhere Workout

    The principal reason I bought the TA2 build program was that I had seen some of James Grage's band workouts on YouTube and was interested in getting a workout program that I could perform when I didn't have the ability or time to get home to workout. I made a small bit pretty comprehensive gym in my house. I have a job that sometimes requires me to stay late or work in a location other than my usual one. Like many others I would find myself short on time to spend with my family and also workout. The resistance bands offer a very good solution to this problem as I can do a workout with the bands during a meal break and have a few areas on my job where I can set up the bands to perform the exercises. The TA2 program provides a good comprehensive base of workout routines with resistance bands that hits all the muscle groups, and you can always make a tweak here or there to make it suit your needs.There was a bit of a learning curve in getting used to finding the feel of the bands to get the intensity I wanted from the workouts but this was only for a couple of workouts into the program. The different feel I get while performing familiar exercises with the bands as opposed to the barbell and dumbbells I use at home make for a nice change of pace to my usual workout routines and I also now include many of the exercises with them in my free weight routines. I also enjoy the core activation you get with many of the band exercises. Would definitely recommend the TA2 build program along with the resistance bands to anyone who is interested in keeping up with their fitness goals and have from time to time little time or room to perform their strength training routines.
