While I’m 100% onboard with the concept of performing exercises that maximize benefits and minimize risk of injury, the reality is that personal trainers are usually the first to hype some new gimmick which does the reverse. Remember having clients jump up onto boxes? What about kettle-drums? Oh, and now: making ropes go up and down. The alternative exercises here may be OK for some types of client but won’t work for many, especially those with limited mobility and limited kinaesthesia. Furthermore, for those wishing to strengthen bones & increase muscle, none of the recommended exercises will work at all.

So, as always, remember there’s no one-size-fits-all. Understand the goals you’re trying to achieve and then read as much as you can about physiology (and maybe see if you can obtain the NASM textbook, which is better than most though still far from perfect) and then see what works best for you.
