If you've got a busy schedule (or you just hate the gym) the best way to tone and strengthen muscles quickly is to do exercises that work your whole body.
In the above video, personal trainer Chris Tye Walker demonstrates five exercises to help you improve your fitness from the comfort of your own home - all you need is two medium-sized weights.
Each individual exercise is designed to work several muscle groups at once, giving you the ultimate workout for minimal effort.
Take two medium-sized weights and stand with feet shoulder-width apart with your weight on your heels.
Put the weights by your shoulders, squat by bending your knees and get ready to feel the burn in your thighs.
Then, extend the legs and once standing, lift one arm across your body, all the way to the ceiling.
Repeat on both sides, exhaling every time you extend.
This will work your abs and shoulders as well as increasing your heart rate.
Come to the floor in a lifted press up position, making sure your hands and shoulders are in line. Rotate your pelvis forwards and keep your eyes down to the floor.
From there, complete the rotation by lifting your left knee to your right elbow, then move back to neutral.
Repeat on both sides.
Stand with your legs just under shoulder-width apart and pull in your abs.
Lunge backwards by placing one leg behind you on the ball of your foot - it's important to keep the knee of the extended leg at a right angle with the floor.
As you lunge backwards, lift your arms from your side to your chest to complete a curl. Be sure to keep your elbows tight to your body.
This will work your biceps, triceps, chest and abs all in one.
Go down to the floor in an extended press up position, then lower your chest to the floor and rise back up again.
As you hit the extended press up position, lift your right hand from the floor and move towards your rib cage, keeping your hand at a right angle to the floor.
Repeat on both sides.
With legs wide, bend and lower the weights to the floor without bending your back.
From there, lift up and extend your arms above your head and behind your shoulders as you hit a standing position.
Lower the weights with control and repeat.
