Which Fitball™ sizes should I buy?
Firstly, make sure to choose an “anti burst” Fitball™, or it’ll all end in tears when performing your 'Sexercise' routine. The Fitball™ come in three sizes- 55cm, 65 cm and 75 cm.
To work out which Fitball™ is right for you and your partner/partners, ensure to sit on it and see if your knees and hips are at 90° angle. If they’re at a greater angle, the fitball™ is too big. If they’re less than 90°angle, it’s too small.
Also it’s important to think about how much to inflate the Fitball™. The more air you pump in, the harder it is to use. So below is a diagram with the right fitball™ sizes for you and your partner to enjoy every minute.
