Programs & challenges
Habits beat heroics: everything here fits in 15 minutes or less a day. Finish a challenge, then keep the 10-minute morning core as your forever default — and let the calorie deficit do the fat-loss part.
Best for: anyone ready to commit to a full month
Four progressive weekly blocks: foundation, endurance, strength, and a peak week that combines everything with cardio finishers. Do the week's block daily (one full rest day per week is smart). Pair it with the calorie calculator — the deficit does the fat loss, the training does the shape.
Best for: total beginners and comeback weeks
One gentle week to wake the core up without soreness that kills motivation. Every move is low-impact and floor-friendly; each day adds one small layer.
Best for: bad knees, small spaces, or just hate mats
A complete week of core work without ever touching the floor. Genuinely effective for obliques and posture — and the easiest routine to actually do in a living room, office or hotel.
Best for: intermediate — you can plank 30s clean
Two weeks of honest strength work built around anti-movement: planks, holds and controlled reps that build the corset. Less burn-chasing, more capability — the flat-stomach look comes from these muscles holding tension all day.
Best for: joints that prefer respect over jumping
Three weeks, zero jumping, all results. Built around walking (the most underrated fat-loss tool), deep-core stability and gentle progressions. Perfect restart after a long break.
Best for: your keep-forever daily default
The routine to run on autopilot after any challenge ends: wake up the core, hit every zone once, and get on with your day. Same order daily; swap any move for its harder cousin when it gets easy.
