You need a trained physiotherapist who practises in a regular gym and can use all the equipment available. Mine has no more than four clients at a time, even though most of us now know our routines. (This may be a requirement of her licence.)Gyms can be dangerous places. A girl broke her arm recently- not on my physio's watch though. As I said before, I am now lifting 24K kettlebells. But the build up has taken six months - two days a week.
