This is a fun one I did it today. Initially, my goal was to complete the circuit 4 times, but I was able to get 2 rounds in! Pretty good for someone who is coming off an injury that basically had me doing none of these cool moves for 3 weeks!
A portable boot and shoe remover. It is positioned at a sloped angle and is roughly varnished for slip resistance. The higher edge has a cut out section into which the heel of the boot or shoe is wedged while the other foot stabilises the device.
