Believe the Hype, its worth it...

I really didn't know if the app would live up to the hype conveyed in the infomercials. But, I was blown away by how effective their programing is.
As a former college athlete, I know my way around a gym. But, in my older age, my usual workouts just haven't been nearly as effective. So I gave Muscle Booster a shot. The workouts, in their basic form, are not hard (some would call them elementary), but, in conjunction with the other movements they are game changers. Made me realize how much more I could stand to increase my mobility.

This fitness program is designed so I feel as if it was designed for me.
It provides an "empathy" for my situation, that helps draw me into the exercise and the desire to do it.

It just isn't for me

It just isn't for me. I am currently undergoing cancer treatments and recently had a total shoulder replacement. Some of the exercises are very difficult. I think I will just stick with what I have with my physical therapy for now.

Chair TaiChai - My story with Stroke Recovery

I would like to provide my short story of recovery. This is a 5* Exercise App; I would absolutely recommend the use of Muscle Booster App; this is when my story starts following a series of 3 strokes each taking a chunk of ability away. After having 15mths with physio’s & O/T’s I was lost & confused thinking this is my life now. I’m an ex runner; martial arts; swimmer & frequent gym user needing to find something to help gain what I’ve lost. I found the Chair TiaChai adverts everywhere so I read up a little. I purchased a 1 month subscription using it initially for 10min per day which was enough to kick start my motivation. I was tired but not exhausted using “Chair TaiChai” & vegans to feel much more confident, gained some coordination, not all of course. I noticed also my strength was gaining day on day with every exercise completed. It was noticeable by family & friends. I would encourage use this app as a light training platform which started personally to regain some independence with my mobility. Especially, those in similar conditions to myself. Chair based exercises is my recommendation to help start your process & start gaining your recovery.

I can't say that the plan doesn't work

I can't say that the plan doesn't work. It's just not for me. That isn't my style of training and getting explanations. Maybe I simply used to a real trainer in the gym and this robotic voice in the app drives me crazy. I'm cancelling my subscription and don't want to be charged further the program. Thanks!
