At Strong Women, we’re forever banging on about the importance of isometric exercise – and with good reason. Isometric movement means moving one side at a time and we do it every day without thinking about it; walking is isometric, as is running for the bus. Cycling is an isometric activity, as is swimming.

The key to being able to do all these activities without picking up a knee injury, rolled ankle or shoulder issue is in balancing strength. You want your right arm/leg/shoulder to be as strong as your left. By making sure that both sides are as powerful as the other, you can reduce the risk of one muscle being under too much pressure.

This workout has an isometric exercise in each section. In the warm up, the world’s greatest stretch will make sure that each hip is equally mobilised. The energiser is a double isometric challenge that will test your strength and balance, and we have two single-sided moves in the main circuit. Oh, and then we finish with a core strength stretch that will lengthen and strengthen each side.
