Very little floor space: a 20-minute session

The point is to fit the work onto a mat-sized patch of floor and finish in 20 minutes, rest included.

You only need a wall. Do not move the furniture if you can take one step toward it.

1. Squat. 40 seconds.
2. Rest. 20 seconds.
3. Wall push-up. 40 seconds.
4. Rest. 20 seconds.
5. Glute bridge. 40 seconds.
6. Rest. 20 seconds.
7. March in place. 40 seconds.

That is one round, about four minutes. Repeat the round four times. If a minute is left, walk the room. Do not add a jump. A jump in a tight room is hard on the neighbours below and on the knees.
