Hey Product Hunt!
I've been working on this app recently with a small team to help people improve their exercise form. There's over 80 exercises aimed primarily for circuit style/HIIT based workouts, with HD videos showing how to perform the exercises and maintain form. All of the advice comes from Ian Williamson, who's represented Scotland in middle-distance running and is also a top-notch personal trainer.
We're planing to add more exercises in the future, as well as expand our existing content by including primary and secondary movers for exercises. We'll also include a body map in an update shortly so you can find the best exercises to work specific body areas.
An Android version is also on the cards if the iOS version proves popular.
Looking forward to hearing what you think!
P.S. We're making the app completely free this weekend to celebrate our launch and so you can try it out fully. The price is still propagating across the App Store so you may need to hold on for a few hours before you can unlock it :)
