Even if you’ve only been training with us a short time, you can probably tell we love jump squats - and what’s not to love? This explosive exercise gives you a full body workout, focussing on developing strength, power and speed. It is precisely because we do jump squats so much that we want to make sure you’re doing them perfectly. Here are a few tips to keep in mind next time we do jump squats in our HIIT training routine: Keep your chest lifted THE WHOLE TIME. Think about rolling your shoulders down and back - you don’t want to round out your spine and keeping your chest lifted will help keep your spine long and strong throughout the movement. Sink down into your heels as deeply as possible. Again, you don’t want to round out your spine, but you also want to make sure you’re working with your optimal range of motion. The lower down you go, the more energy you will use and the more muscle fibres you’ll work. End result? A better workout. Jump up as high as you can, bringing your arms into the air above your head. This forces you to use more energy and you’ll burn more calories. Engage your core. Don’t get sloppy here. Engaging your core will not only give you the best ab workout, but it will also help protect your lower back against injury and stabilize the entire full body workout. ABOVE ALL: Listen to your body. If your knees hurt, take out the jump. If your lower back hurts, only sink down and back as far as comfortable.
