Bonney’s favourite: Reaching for a TRX suspension trainer. To do triceps extensions with TRX, face away from the anchor point with your hands in the handles and thumbs at temple height.

Bodyweight Triceps Extension This bodyweight exercise is gentler ... Lower slowly for 3 to 4 sets of 12 to 15 reps. With TRX bands, grip the handles and extend your arms while leaning forward.
