Well thought out activity plan

Well thought out activity plan, which is supplemented with daily 'gentle' reminders.
Took the plan out for over a year and worked at it as scheduled. Didn't achieve my goals but felt that it was beneficial.
in the end, just thought it too expensive for an automated system.

Easy to follow and wide selection of activities and you don't end up killing yourself

Easy to follow and wide variety of exercises or whatever you want to call them. AT 82 there are things I cannot and will not do because my body doesn't have the flexibility nor the strength. With this tool I can pick and choose what works for me. I do wish when you miss an exercise it was easier to go back and start it over. I end up missing the next one too but I guess that's just an old man learning to use the software better.

It’s an easy workout

It’s an easy workout, the morning routine from the challenges I do every morning and it helps me get moving for the day every day it’s only 7 minutes but it does my body great. I do the hardest level and for strength every other day and it’s increased my size a little which is what I was looking for and it gets everything tight. It’s surprisingly done everything they say and I’m very happy and impressed with the results. The workouts get mixed so you do different things all the time working on the whole body.

Effective adjustable workouts made just for you!

I love that you can create your own workouts and add various equipment if you want or need to. I like that you can like or dislike each move after each workout and the app adjusts your workouts. I get a lot of ideas from the workouts they suggest. You can also keep track of your nutrition and calories throughout the day. I like to be able to follow along with someone that helps with time, pacing and accountability.!

I personally do not like the program

I personally do not like the program. Most of the workouts are poorly explained and some I physically can't do. There is no time between the exercises to figure out how to do them and the pictures are terrible. I don't like the fact there is no one available to contact for help. Your program is vert impersonal.

Hello John,

Thank you for sharing your feedback.

I understand your concerns about the workout instructions, the limited time between exercises, the exercise images, and feeling that some of the workouts are beyond your current physical abilities. I'm also sorry that you felt there was no one available to help you—that's certainly not the experience we want you to have.

I've already reached out to you via adam.support@muscle-booster.io so we can discuss your concerns in more detail and work toward a solution together. Please check your inbox (and your spam or junk folder, just in case) and reply whenever it's convenient for you.

I look forward to hearing from you and helping further.

Very good, For me, the ideal app.

Very good app where you can choose your own level and indicate whether you find an exercise okay, or just too easy or too heavy. Easy-to-perform exercises for everyone. For me, the ideal app.

I signed up for a trial period

I signed up for a trial period. Had difficulty using the program. Got notice of monthly billing. Requested a refund and cancellation. I was able to finally access customer service and was advised that my account is cancelled and that a refund will be processed. Just a waste of my time.
