    TA2 Build

    This program is awesome. I got this program when I ordered the bundle that included the bands. I am four weeks in on the program and can't wait to tackle each workout. Don't be fooled by bands when you first start out as they will humble you pretty quick. Thanks for a great product.

    Best Bands on the Market, hands down

    Best bands, best workout, best customer service, lifetime warranty, this is the whole package… I have been working out for the last year with free weights and have recently switched to resistance bands for the simplicity and portability of it… what I have discovered is that I am not only enjoying the workouts using the bands, but I am feeling soreness post workout that I haven’t felt in a long while… they really do give you an incredible muscle building workout. Thank you Undersun!

    Finally Found Something That Works For ME!!!

    The muscle building band set is simple and easy to use! I have regular breaks at work, so I hooked the band retainer to the back of my truck and I exercise in the parking lot every break! It works for me because it's not about making time to work out - it's about working out when I have time! I noticed an absolute change in my physical and mental fitness almost immediately. Additionally, I have a combat related back injury that cannot be repaired, however strengthening my back muscles keeps the pain at a tolerable level. This is the first fitness product/program I've found that actually, consistently helps me live an almost normal life! Thanks Undersun!!

    A Happy Beginner

    I'm 63 and just beginning to start an exercise regimen. I used to be in shape but have been consumed with my work life for the past 25 yrs or so. I stumbled upon Undersun Fitness on YouTube and was impressed, so I purchased a beginner set. So far, and I've only had them a week, but I really like the way the bands feel through the whole range of motion of the exercises I perform. The flexibility the bands create, changing angles on different exercises keep things fresh. I'm really glad I made this purchase! Thanks Undersun!!

    Undersun bands and TA2 program are challenging.

    I am grateful for the band weight and the programs offered for training. I had several severe injuries to my body in my 30's leaving me with damaged nerves and muscles. The band training allows me to have a safer and better workout than I ever did using weights. I am more motivated now than I have been in the past to get healthier, stronger and in shape using Undersun bands. I am able to do the routine in the morning and go about my day. Afternoons in the CA desert can be a challenge, but the ability to work out in the sun provides more motivation for me. I know of my imbalances from my injuries, the band weights allow me to work out and develop more functionality relating to every day moment in my life.
