It's also suitable for individuals seeking structured home workouts, especially those over 50, who appreciate the convenience and personalized pace R38R56.

Skip / stay free if

You should skip paying if you are sensitive to high subscription costs, as many users find it overpriced R2R4R89R229. Also skip if you are concerned about shady billing practices, auto-renewals, and poor customer service, which are frequently reported R12R16R20R21. Users looking for diverse workouts, detailed form instructions, or seamless integration with other fitness trackers might also be disappointed R4R13.

Evidence note: The reviews are heavily skewed towards billing and customer service complaints, which are numerous and detailed. While there is praise for the workouts themselves, these positive aspects are often overshadowed by the negative experiences with payment and support. The lifetime rating of 4.5 is higher than what recent reviews suggest, indicating a potential decline in user satisfaction or a persistent issue for a segment of the user base.

  1. [R4] 1/5 · US Workout: I like some of the workouts but there seems to be a lot of repetition. I don’t like how you can’t go back and see a workout if you missed it. I also don’t want to pay $20 a month.
  2. [R2] 4/5 · US Gud experience: Bite expansive for me
  3. [R89] 2/5 · US Overall quality: While I found the workouts to be helpful, they are grossly overpriced. $40 a month… seriously??
  4. [R229] 3/5 · US Good app but expensive: I like the app and following along. Works the whole body. Just a little too expensive to use long term after the promotion month.
  5. [R16] 3/5 · US Questionable Billing practices: This app avoids the Apple subscription service and bills you directly through a website. We canceled this and we’re still billed for a month service. We were told that we were. ‘Eligible’ for a refund even though we canceled. It’s clear why they are avoiding Apple subscription service. My bank even flagged this as fraudulent. I would consider strongly before subscr
  6. [R20] 1/5 · US Tricky and not good: I tried the app, and didn’t meet my expectations- forgot to cancel, the got charged $38.95 euro which felt abusive since initially it say it’s 14.99 month….be careful
  7. [R21] 1/5 · US Scam: Beware this ap will charge your card a month after you download it !!
  8. [R22] 1/5 · US SCAMMERS: While they may indeed offer some exercises etc they offer zero accountability and make canceling very difficult. Take a photo of when you cancel because you will likely receive another charge the next cycle. And when you cancel that again and contact them the same day as the charge they will refuse a refund, refuse to acknowledge your previous cancellation. Had to get credit card co i
  9. [R6] 2/5 · US Great app, poor support: I’ve used this app for nearly 2 years and had great results with the workouts. Seems like if you have a technical problem you’re on your own. The app just stopped working one day. Probably from the latest update. Reaching out to support for several days just got me automated emails pointing me to a FAQ. Following the guidance in the FAQ made the issue even worse. A
  10. [R25] 1/5 · US SCAM: Never signed up for monthly membership. Downloaded app only and it charged me. I've been charged $40 for a monthly fee and have never used it. Contacted them and they WILL NOT ISSUE A REFUND. Never had a company do this. BUYER BEWARE. Plenty of other fitness apps out there, choose one with better customer service.
  11. [R36] 1/5 · US Hidden charges not refundable: Got automatically signed up for expensive renewals and was not refunded. The only customer service reachable is an AI bot.
  12. [R37] 5/5 · US Absolutely not worth you money: Signing up for this app is a not recommended. They will attempt to charge you extra money for over the top expensive services that you do not want. They will not discuss refunds or send reminders for upcoming billing. All services are on auto renewal so keep an eye on your account. Exercises are so-so and they completely over exaggerated how much actual involvement
  13. [R97] 1/5 · US Too many upsales!: Is quite annoying you sign up for one thing and then they are asking to signup for another and then another. A log of hidden services they are constantly pushing and makes me feel highly uncomfortable.
  14. [R3] 5/5 · US Senior Chair Tia chi: I am a 75 yr old male who is in the 3rd week of the Muscle Booster program. I use MB to supplement my regular Tia Chi for Seniors. So far I have lost 6 lbs and can feel the benefits. So far, so good, so happy. Thanks
  15. [R5] 5/5 · US Great program! Very detailed and complete! Now it’s up to me!: Love it!
  16. [R7] 4/5 · US Amazing App: Life changing
  17. [R10] 5/5 · US Getting fit: This 70 yr old let myself go for a few years. Going to Disney for vacation & was afraid I'd be harpooned if I went in the water. On a 11 week streak of Thai-Chi chair workouts & supplemental workouts. With watching what I eat & exercising I'm losing weight! Being 70, I did low impact and this program is great. Kudos to designers and welcome to seniors looking to get fit
  18. [R23] 4/5 · US Over 75 workout: OK, I’m old. Most of the workout is pretty straight forward and easily doable, except as an older person, our balance decreases with age making some movements difficult to do without falling. Often if I’m supposed to do 10 reps, I may only get 5 or 6 in. Also, any exercise laying on the floor, I have to do laying on my bed, so I’m able to get up easily when the exercise is finishe
  19. [R27] 5/5 · US Low impact chair exercises: This is a great App with wonderful seated and chair workouts. Very helpful for those with lower back issues, from stretches, to body weight workouts prefect fit for a daily routine.
  20. [R38] 5/5 · US Great app!: 57M. Like a a lot of people, I saw the add and did the trial. After 2-1/2 months, it’s been incredible. I quit my gym and focused on this app, working out at home. The ad was right, for guys like me over 50, the gym can be about ego and not functional strength. More power to the guys my age who hit the gym, but this is working. Combined with a strict diet I had already been on, this wo
  21. [R47] 5/5 · US Convenient Exercise Program: Muscle Booster helps me exercise my entire body without needing to go to a gym. I am not a couch potato, but am very active cycling and an advanced pickleball player, however, I am in my 80’s. I start my day - everyday - with Muscle Booster to keep me in shape. Very worthwhile program and very adaptable to different needs.
  22. [R56] 5/5 · US LOVIN’ IT !!!: This workout app is phenomenal for my at-home needs. I live 45 minutes from the closest gym, so this offers a great routine without having to leave the house. I would highly recommend the workout regiment to anyone who’s looking to get busy exercising.
  23. [R59] 5/5 · US It became my daily routine: I’ve been using this app for about six months now, daily. I am 72 and I love to start my day with it. I like the workouts and the app delivers. Update. Year 2: I am on my second year now. I airplay it on my big tv screen and makes me feel at the gym in the comfort of my house. I like the sequence of warm up, to workout to cool down . I like the variety it mixes in my
  24. [R14] 5/5 · US Great: Great option and wonderful customer service experience.
  25. [R26] 5/5 · US Responsive: Had some initial questions to get started. Sent via email. Got a quick response.
  26. [R41] 5/5 · US Great customer service!: I accidentally bought two subscriptions and the customer service was quick and very helpful. They very nicely canceled my subscription and kept the one that would be the best deal for me! I was pleasantly surprised that an app would have such great customer service ! They were also kind when I emailed multiple times. Very impressed!!
  27. [R42] 5/5 · US Get some: The app is awesome! The people who work there and better!
  28. [R31] 4/5 · US Gets me moving: I find this plan easy to follow with video assist. I wish I could screen Cast it to my TV instead of looking at my phone. It’s a workout tailored for each individual and can be tweaked to my comfort level. I like it so far.
  29. [R35] 4/5 · US Seeing results through consistency: I have used this app regularly for almost a year now and through consistency. I am seeing results. The app makes it easier to ensure you have proper form due to its excellent graphics. Overall I like this App. I am a little disappointed about some of the tai chi workouts, which seem too easy or basic as compared to the advertisements that you see online.
  30. [R64] 5/5 · US Awesome workout: This is like having a personal workout coach pushing you during your workouts. It also guides you on the proper technique to use. I use this app for 30 minutes each morning before I get my day started. I can see a huge difference in my abdomen and chest.
  31. [R12] 1/5 · US Shady auto renew scam out of Cyprus.: If you were interested in trying the program for a month to see if it gets results, be aware they automatically charge even if you cancel and do not sign up for auto renew then make refunds very difficult. Shady company out of Cyprus. Do not purchase without being aware/
  32. [R19] 5/5 · US Get this app!!!: I absolutely love this app and the workouts it builds for me. I’m giving it five stars but if there’s one thing that I would want to change, it would only be that I’d be able to track the weights amount I’m lifting on each workout to track how much stronger I’m getting overtime. I’m 10 weeks in and I can’t wait to see the improvements I make over the next year.
  33. [R13] 1/5 · US Developer keeps changing functionality: I loved this app, but the developer keeps changing functionality back and forward. I got used to a routine just to completely change it next update.
  34. [R226] 3/5 · US Does the Job: At first, Muscle Booster felt like the perfect training partner. I’ve been working out for most of my life, so I was looking for an app that could give me structured workouts and introduce new exercises to keep things fresh. During the first two weeks, it delivered exactly that. The workouts felt new, engaging, and well put together. However, after those initial weeks, the experienc
  35. [R237] 3/5 · US Same workouts: Same workouts no variety, it’s great to start but it’s not a good app for long term workouts.
