Chest press is one of the most common exercises to work on the large muscles on glutes and chest muscles. Adding stability ball in the workout is another challenge for the performer. Chest press on stability ball increases your balance, coordination and focus. Stability ball takes your exercise to a more challenging level to strengthen and tone your targeted muscles. The element of instability requires more activation of core abdominal muscles during the workout that increases the strength of multiple related muscles. The increased involvement of core muscles can assist in improving posture, burn body fats and reduce injury risks.
