Liz Earle relies on these 3 exercises to stay in the 'best shape of her life' at 63 - here's how to do them

In recent years, Liz Earle has become perhaps as well known for her wellness advice as her beauty knowledge. The 63-year-old entrepreneur says she's focused on strength training to improve her longevity and stay independent later in life.

However, there's no need to spend hours in the gym to achieve these goals, she says. In a video on her YouTube channel, she said that short, consistent sessions of up to 20 minutes can make a "massive difference".

"I've genuinely changed my shape with just a few simple exercises - I've built up the weight (and reps) over several years. And it doesn't need to take hours - you just need to be consistent!" she says.

Liz shared a three-part workout featuring one compound movement and two isolation upper-body exercises you can do at home.

Tricep dips

Tricep dips are a bodyweight exercise that works the muscles on the back of your arm. You can make the exercise easier by moving your feet closer to your body. The further away your feet are, the harder the exercise will be.

Here's how to do it:

• Sit on a stable chair or bench and position your palms on the flat seat about hip-width apart. Your fingers should curl over the edge of the seat.
• Drop your hips over the edge, keeping your body close to the seat.
• Extend your legs out in front of you and rest your heels on the floor.
• Brace your core and lower your hips toward the floor, stopping when your upper arms are parallel to the ground if you can.

Hammer curls

This is a variation of a bicep curl that focuses on strengthening the muscles that help you bend your elbow and those in your forearm, as well as the muscles in your arm. Compared to a regular curl, it's also easier on the wrists.

Here's how to do it:

• Grab two dumbbells, one in each hand.
• Turn your hands so your fingers face each other and your knuckles point to the front of the room.
• Hinge very slightly at your hips, keeping your knees soft. Brace your core.
• Lift the dumbbells together or one at a time towards your shoulders.

Press-ups

If you're not confident doing a full press-up, drop your knees to the ground when you're in the plank position. This offers support. Alternatively, try doing the exercise resting on your kitchen counter. The further you move your feet away from the counter, the harder the exercise will be.

Here's how to do it:

• Come down onto your yoga mat in a plank position, resting on your hands.
• Make sure your core is braced, your back is straight, and your tailbone is tucked.
• Lower your chest by bending your elbows until it's a few inches from the floor.
• Push through your hands to return to the starting position.
