Just one dumbbell and 20 minutes are all you need to train your whole body

Trainer Brittany Williams has put together a brilliant workout routine that you can personalize to your own needs. She's demonstrated 10 full-body exercises you can mix and match for a heart-pumping 20-minute session.

The moves are all compound exercises, meaning you work multiple muscle groups at once and get a full-body workout in a fairly short space of time. If there’s a move that doesn’t work for you, you can simply skip it and choose another.

She suggests picking five to six out of the lot and using them to build your own, personalized session.

How to do the workout

• Alternating step-out snatch

• Sumo squat bicep curl to raise

• Split squat tricep extension

• Offset Romanian deadlift to upright row

• Lateral pullover crunch

• Birddog row

• Chest press scissor switch

• Kneel to squat

• Tricep skullcrusher supine march

• Chest press glute bridge

Pick five or six exercises out of the above suggestions and do 10 repetitions (or eight on each side for single arm or leg exercises) for four rounds. If you want more of a challenge, you can attempt to do all 10 moves.

What are compound exercises?

Compound exercises are multi-joint movements that engage more than one muscle group at once, making them an efficient alternative to isolation exercises (where you only work a single joint and one muscle area at a time).

Speaking previously with Fit&Well, trainer Chelsea Labadini explained that compound exercises can help you efficiently build strength across the body in a short space of time.

"The beauty of compound exercises is they work for everyone," she said. "As you get stronger and more confident with your form you can progress the exercise by increasing the weight or the amount of repetitions you do."

"If you are a beginner or have no access to equipment, then you can use your own body weight as resistance for compound exercises. This includes exercises like squats, lunges, split squats, press-ups, and pull-ups."
