Back to Gym is a 12-week plan for getting back to the gym and staying this time. It starts lighter than you think, asks how you feel before each session, and changes the plan when a week goes wrong. It logs food too: Indian dishes, food from other cuisines and packaged foods by barcode.
There's no account. Your log is kept on your iPhone, and your sessions and plan sync through your own iCloud. We can't see any of it.
This is a test before the app goes into the App Store. Use it for your real training and meals for two weeks, and tell us what gets in the way.
