Even with supermodel genes, Rosie Huntington-Whiteley has to work for her abs. Here, her personal trainer, Simone de la Rue, reveals her secret tips to toning up in all the right places. The best bit? You can do it all from the comfort of your home
“Resistance training is a great way to increase your strength and tone up without needing heavy weights,” says Simone de la Rue of Body by Simone. “This clever piece of kit  – essentially reinforced rubber bands – is easy to travel with and will help your coordination and balance. Try the simple exercise below.”
THE WORKOUT: BICEP CURLS
1) Grab a resistance band with handles and stand on the elastic with your legs hip-width apart, knees slightly bent.
2) Bend your elbows, curling your hand up towards your shoulders while hugging your elbows to your torso.
3) Lower your arms slowly, resisting the pull of the band as you return to the starting position.
4) Start with three sets of 10 reps to create long, lean muscles.
“Looking great on the beach is usually the main goal for any core workout, but there are other benefits, too,” says Simone. “Ab crunches not only strengthen your core, they can prevent injury and back pain, protect your organs and also help to maintain a ballet-like posture. The gain is totally worth the pain!”
THE WORKOUT: AB CRUNCHES
1) Start by lying on your back, then raise one arm and opposite leg to the ceiling.
2) Raise your body off the ground as you reach for your toes, keeping the leg and arm lifted. You will feel this in your abs.
3) Lower everything back down to the mat, tucking the chin to chest to take the strain out of your neck.
4) Repeat 30 times on each side.
“Stretching helps keep the muscles flexible, strong and healthy while increasing blood flow and circulation, sending oxygen to the brain for a clearer mind. It’s extremely important to warm up before any activity and cool down afterwards,” says Simone. “Add in a yoga session to your weekly workouts to really feel the benefits.”
THE WORKOUT: STANDING TRICEP STRETCH
1) Stand with legs hip-width apart and with a slight bend in the knees.
2) Place your right hand on your upper back with the elbow bent towards the ceiling.
3) Support the elbow with your other hand and relax the shoulders away from the ears.
4) Inhale, reaching upwards and exhale, bending the upper body to the right.
5) Hold for five deep breaths, slowly return to centre and repeat on the left side.
