I have been reversing 30 years of growing fat at a high-pressure desk job! I started with the Knees over Toes guy on YouTube, strengthening my legs with a backward treadmill and leg exercises, then with the Low Back Ability guy on YouTube with back extensions and more leg work! I dropped a lot of weight and got healthier! I needed something to help with cardio and HIIT, and saw Coop's review on YouTube about the Strive Air Bike. I never would have considered a standard air bike because the effort would be too much for me right now. Well, in the couple of weeks I have had the bike I have moved from level three steady state to level four, and put three 20-second sessions of all-I-can-do HIIT in a ten minute workout. My pulse recovery has improved in just two weeks! The bike is incredibly well made and has a place of honor with my backward treadmill. So happy for this purchase! FWIW, I use a Polar 0H1 arm pulse monitor and the Thrivify Connect app to record my sessions; they work great together with the bike! Enjoy!
