Best Workout Program

Steel fit workout program is one of the best programs I have been part of. Hayden Steel’s workout videos and his explanation / instruction on how to do the lift, why the lift is done a certain way is phenomenal. The time and effort he has put into this APP shows how much he believes and cares about his program. I am 51 and the workout is joint friendly and at the end of each workout you feel the work you put in. I would recommend this program to anyone looking for a program different than the same old programs everyone else is doing. Trust me this is one of a kind.

Worth Every Penny!!!

This is, by far, the best course you can get anywhere on building strength and muscle. Hayden’s passion for imparting his knowledge to his students is truly inspiring. Over the years, I’ve spent way too much money on personal trainers who literally did nothing more than make up different workout routines and stand next to me in the gym counting reps. Since starting the MGB program a few weeks ago, I’m already experiencing new muscle growth and a renewed enthusiasm for working out. I finished each workout now with my muscles completely fried yet I can’t wait to get back into the gym the next day! I only wish I had known about MGB sooner. Thanks Hayden!!!

Great app, Great workouts

I can tell a lot of time and effort was put into this! The app is pretty straight forward and very detailed. I love that if I have questions, I can ask in the community and Hayden himself will answer. The workouts definitely put your muscles into growth mode, and I’ve seen a difference in the way I look and feel by implementing Hayden’s instruction. This app is a personal trainer in your pocket!

Arms program

This is one of the best programs I have ever done. The amount of content is ridiculous. This is the best program in the App Store.
