When it comes to exercise and fitness, there is a misconception that it can cost a lot of money to get into shape.

But according to Karl Henry, that is not the case at all.

The personal trainer and Operation Transformation star is a firm believer that everyone can exercise and achieve results at home without spending a penny.

Fitness guru Karl has shared five exercises that will help tone areas of the body such as the stomach, arms and thighs without signing up for a gym membership.

“People sometimes think exercising is really expensive but we blow that myth out of the water. Your body is a weight, so use it,” Karl tells RSVP Magazine.

“These exercises are really simple, and free and that’s a crucial thing. Everything our Operation Transformation leaders do and the results they get is all from doing free simple exercises, and if you do those, work hard at it and eat well you can get really good results in a couple of weeks.”

Here are Karl’s five free exercises you can do yourself at home for a toned stomach, arms and thighs.

Press Ups

Karl says a press up is a brilliant exercise that works all parts of your body. Begin with your chest and stomach flat on the floor, exhale as you push up from your hands and heels, pause for a second in a plank position with your core engaged, and inhale as you slowly lower back to your starting position.

Squats

A squat is a really simple exercise which will help tone your thighs and legs. Stand with your feet shoulder width apart and toes pointed out. Send your hips back and squat down with your thighs parallel to the floor while keeping your chest lifted. Stand back up and repeat.

Lunges

Lunges will help keep your legs in shape. Start by standing tall, step forward on one foot until your leg reaches a 90 degree angle. Keep your rear knee parallel to the ground while your front knee shouldn’t go above your toes. Lift your leg to the starting position and repeat with your other leg.

Tricep dips

Tricep dips will keep your arms in shape, but you need a surface in order to do them, such as a sturdy chair. Sit on the chair with your arms shoulder width apart. Move your bum off the chair and use your arms to support you while stretching your legs in front. Lower yourself by bending your elbows back until they reach a 90 degree angle. Straighten your elbows fully to lift yourself back up and repeat.

Straight arm plank

This exercise will tone up your stomach. Firstly, get into a plank position and support your body weight on your hands and toes. Hands should be placed directly under your shoulders. Keep your core engaged and hold the position for as long as you can.
