The best exercise routine is the one you still do in three months, which is almost never the ambitious one. Most people start with an hour a day, six days a week, and quietly abandon it inside a fortnight. What follows is deliberately small, because small is what survives contact with real life, and on keto it is plenty to hold on to muscle and support fat loss.
The one habit that matters most: walking
If you do nothing else, walk. A daily walk is the most forgiving exercise there is: it needs no kit, no recovery, no changing your clothes, and it suits the steady energy keto tends to give you. Aim for twenty to thirty minutes a day, ideally after a meal, and let it be unhurried. Walking burns fat, helps blood sugar, clears your head, and is almost impossible to overdo or to dread. Build everything else on top of this, not instead of it.
The fifteen-minute session, three times a week
Alongside the walking, a short bout of resistance work three times a week, say Monday, Wednesday and Friday, keeps your muscle while you lose fat. No gym, no equipment. Do each exercise for the suggested reps, rest a moment, then move to the next, and run through the lot twice.
- Squats to a chair, ten to fifteen. Sit back as if to perch on a seat, then stand.
- Press-ups, as many as you can with good form. Drop to your knees, or push against a wall or worktop, if floor press-ups are too much at first.
- Glute bridges, twelve to fifteen. Lie on your back, knees bent, and drive your hips up.
- A plank, hold for twenty to forty seconds. Knees down if needed.
- A short carry or march on the spot, thirty seconds, to finish.
The whole thing takes about fifteen minutes. That is the point.
Make it easy to keep
Pick fixed days and a fixed time, because deciding each day is what kills routines. Lay out the half-square of floor you need the night before if that helps. Most importantly, treat a missed session as nothing at all: skip it, do the next one, and never try to “make up” for it with a punishing double. A routine you resume after a gap is a routine you keep for years; one you feel guilty about is one you quit.
Progressing without overhauling
When the sessions start to feel easy, add a little rather than a lot: one more round, a few more reps, a slightly longer plank, a heavier shopping bag in the carry. There is no need to redesign anything. The keto side of this is covered in the exercise on keto piece, including why your stamina may dip for the first couple of weeks before it settles.
