Get in the swim
Swimming is in a league of its own. It’s a cardiovascular workout that achieves the incredible feat of targeting every muscle in your body while putting virtually no pressure on your joints. If you want to instantly improve your swimming buy some goggles. They’re vital to help you relax in the water. If you’re squinting, your neck muscles are tense and you’re much more likely to hold your head out of the water which puts pressure on your back. But don’t buy cheap ones – it’s a false economy; they’ll leave marks on your face and fog up easily so you won’t wear them.
