Here is a fantastic, highly effective 4-week full-body workout plan designed exactly for a spare room or home gym.

All you need is your pair of dumbbells, your own body weight, and about 30 minutes a day!

To keep you progressing over the four weeks without spending hours working out, we will use a circuit format. This means you will move from one exercise to the next with minimal rest, which keeps your heart rate up, burns calories, and builds strength all at the same time.

The Weekly Schedule

Aim to complete three full-body workouts a week, resting for at least one day in between sessions (for example: Monday, Wednesday, and Friday).

Warm-up (4 minutes): Light jogging on the spot, arm circles, bodyweight squats, and jumping jacks.
The Main Circuit (22-24 minutes): Perform each exercise for 40 seconds, followed by 20 seconds of rest to transition to the next move. Complete 4 total rounds, resting for 1 minute between each round.
Cool-down (2-4 minutes): Gentle stretching focusing on your legs, chest, and back.

Throw on a great playlist, grab a water bottle, and enjoy having a full gym routine right at the end of your hallway!

How to Progress Over the 4 Weeks

To make sure your body keeps changing and adapting, you need to challenge it a little bit more each week. Here is your 4-week progression map:

Week 1 (Familiarisation)

Focus purely on your form. Don't worry about how heavy the weights are or how fast you move. Stick to the 40 seconds work / 20 seconds rest timing.

Week 2 (Pacing)

Try to get 1 or 2 more repetitions into every 40-second working window than you did in Week 1, while keeping your form absolutely perfect.

Week 3 (Intensity Shift)

Time to turn up the heat! Change the timer to 45 seconds of work and 15 seconds of rest. This gives you more time under tension and less time to recover.

Week 4 (The Overload)

Keep the Week 3 timing (45/15), but try to increase the weight of your dumbbells for exercises like Squats, RDLs, and Rows. If you have adjustable dumbbells, turn the dial up one notch!
