Success tips
• This is an important exercise but can
become high risk if done incorrectly.
• Keep the chest lifted and always
maintain a good spinal alignment with
a very slight arch in the lower back.
• More range of motion is not
necessarily better, especially in this
exercise.
• Move only as far as your muscles can
take you. Try to eliminate uncontrolled
momentum.
