Set-up: Set up gripping the suspension handles at shoulder width or slightly wider - so that the upper arms are tucked at 45-degree angle to the torso - and fingers pointing forward. With the toes together and hips up, establish proper upper body posture with a neutral back.
Movement: Press the chest up until the arms are straight, then return to the starting position. Cue the descent by attempting to 'pull' yourself down to the floor with your shoulder blades. Adjust difficulty by raising or lowering the height of the the suspension handles.
Emphasis: Don't allow the hips or the lower back to sag. Don't let your elbows flare out to the sides. Use a complete range of motion, bringing the chest to the rings. Don't push the head forward to the floor.
Optional weighting: If additional difficulty is needed after lowering the handles - and or elevating your feet - external resistance may be added to the exercise through the use of a weight vest, chains, or even a snug and sturdy loaded back-pack.
