Alignment is maintained in back.
Careful in end phase of the pushdown, as there is a tendency to flex the upper back.
Use chair arms to limit the distance of the ‘dip’. Caution with any wrist and shoulder dysfunctions.
Change position to below shoulder level – use two individual dumbbells or theraband.
Avoid heavy single dumbbells in this position. Better to use two lighter weights
The image above is not an effective triceps stretch
Triceps stretch overhead encourages thoracic flexion so should be avoided as well.
Could also use the wall to assist.
