Comments and tips
To minimize the pressure on your shoulder joints, keep your elbows a little lower than your shoulders.
Some chest press machines have a foot lever that will help you to push the handles forward from their resting positions, making them easier to grasp at the start of the exercise. Otherwise, you’d have to stretch your arms far back to grasp the handles. After you grasp the handles, you have to release the lever before starting to press. Once the set is over, you have to use the same foot lever to brace the handles and lower them back to their resting positions without having to stretch your arms far back.
The machine chest press is great if you want to push very heavy weights with your chest but don’t have anyone to help you with the barbell bench press. Otherwise, the barbell bench press is favorable to the machine chest press. The reason is that the barbell bench press necessitates the recruitment of more stabilizer muscles. The machine chest press is also great for beginners, the elderly, and people undergoing rehabilitation.
