Complete 50 Jump Squats in a row without stopping! And these are thigh parallel jump squats. If you don’t go that low – it doesn’t count. So for those needing some guidance on how low they must go – we are happy for you to use a tyre or low bench to do a touch down (no weight put on the bench or tyre) so know how low to go! 3 strikes (as in – 3 times you don’t go low enough) and you unfortunately have to start again.
