Decathlon Nyamba Reversible Balance Station £64.99

Core strength is hugely important in the golf swing – a stronger core means you have greater stability and a better starting point from which to make a confident and powerful swing. This is a fitness tool that gives multiple exercise options for increasing core strength.

It’s a low-cost version of a BOSU ball, which stands for Both Sides Up. You can use it either dome or flat side up, with the common factor its ‘wobbly’ nature that tests your balance on every exercise and means you have to engage the core muscles that play a major role in the golf swing.

This Decathlon version is about half the price of the ‘official’ BOSU ball, but its functionality is pretty much the same. It comes with some detachable resistance bands with handles, which give you more options to help tone your upper body. The number of really useful exercises you can do with this piece of equipment is phenomenal.
