This is very second hand so forgive me if I am wrong but I’ve heard that Holmes Place, a major gym chain in the UK have pulled swiss ball out of their gyms.
The story told to me was that a man was performing DB side raises whilst kneeling on a ball, he fell off, broke his neck, and died as a result!
It might be cruel to say but when you hear about people losing there lives benching or getting seriously injured squatting I tend to think that at least they were doing a worthwhile exercise, not attempting some poxy swiss ball balance trick!
I just wonder what the chekkie-fied Holmes Place gym instructors are going to teach there clients now? It’s probably back to the treadmills and steppers for the members!
