Hello Graig,

We appreciate you sharing your thoughts on the Tai Chi chair program. We understand it wasn't quite what you expected for an exercise program. We are always working to offer a variety of options.

You can find the Tai Chi Workout Challenge in ‘Challenges’ tab.

If you’d like to share more feedback or have any questions, feel free to email me at adam.support@muscle-booster.io with the subject line "TP review".

Its an ok app with easy exercises

Its an ok app with easy exercises. Rest times inbetween each ones . You dont need to rest there is an option to carry in to the nest exercise if you wish. Different options of difficulty. One massive drawback no exercises for the arms even though there is a full body option which I do. It still doesn't cover the arms. Been doing it for 15 days, started of a couple of days doing 7 minutes then 20 now up to 30 mi utes sessions. Haven't seen any noticeable change looks wise or scale wise but am feeling more flexible . Helping with the fibromyalgia!

First class ethics

Having purchased an initial plan and realising it would be too difficult for me, due to health issues, I got charged for a qtrly renewal, as I lost sight of it being a renewable subscription. These guys were completely understanding and sympathetic to my situation, and agreed to refund me. Very impressed with such an ethical approach to personal circumstances

I like the program so far

I like the program so far, approaching 2 weeks in but wish there would be a bit more during the exercises about which muscle groups should be emphasized or felt, so it is easier to know if I am doing things correctly
