Off the wall can mean different things. Sometimes it’s necessary to mix things up with clients to keep it fun, interesting and get them coming back.
Health in the gym can be somewhat monotonous, so breaking the ice every now and then really helps.
Ive seen lots of things I would consider to be bad, but the biggest one is when a trainer gets into teaching a teen how to lift. Usually I have seen crossfit type workouts. Advanced multi joint movements, at speed for reps.
Great for an athlete, but usually teens dont have the neuromuscular foundation to work like this. It sets them up for some bad gym experiences.
