These are a smart starting point, not a life sentence. Run them for one to two weeks, watch your weekly weight trend, and adjust from there. Day-to-day movement moves your burn more than the gym does.
Want these emailed to you with a 7-day starter plan built on them?
Want these tracked, with Jack reading your real results each week and suggesting when they should move (you decide), plus a full program to go with them? That's exactly what the app does.
