I would sequence very carefully and mix things up so that you are not doing consecutive exercises that require wrist flexion repeatedly.
TRX is great but I feel it can be restrictive so I would mix it up with other forms of exercises such as free squats and lunges, jumping jacks etc in between
I would also be very detailed in explaining set up and watch shoulders and knees.
As in any group class I think mixing up muscle tension and pace keeps your participants alert and wondering what’s coming next.
For instance: do plank without the TRX, then do Plank with feet in TRX but modify by holding plank along with doing “bicycles”
