Bench Push-Ups
At a kitchen bench, rest hands on edge and elbows straight, step back until your shoulders are right angle to your body.
Keeping your body steady, lower yourself forward with the elbows bent out in line with hands. Stop when pain or not able to hold body or shoulders steady. Push back out.
Repeat 10x daily until you can allow your chest to reach bench and body and shoulders are steady. Then every three days add 4 additional repetitions until you are doing 30 repetitions daily.
