Fitness ball sit-ups mainly exercise abdominal muscles.
The action is basically the same as ordinary sit-ups, and you can take the posture of crossing your hands on your chest or gently supporting your ears.
Doing sit-ups with fitness balls can make the upper body rise more, thus reducing the difficulty of movement.
It is more suitable for fitness "freshmen" or girls, so it is the best choice for girlfriends to exercise together.
Ideal number of groups: 30/ group, 3~5 groups.
The researchers tested the strength of these college students' front and rear abdominal muscles and lower back muscles, the flexibility of abdominal muscles (rectus abdominis) when doing sit-ups, the flexibility of back muscles (erector spinae) when doing back flexion and extension, and the ability of body balance when standing on one leg. Although the effect of the treadmill group and the training ball group in improving strength is similar, the latter greatly improves the flexibility of muscles during training and can ensure a longer balance when standing on one leg.
Be an expert in training balls
According to the research of Springfield University, you should not hesitate to add some moves on the ball in training. Occasionally using the training ball in sit-ups and back flexion and extension exercises is definitely better than training on the flat ground all the time. In addition to the benefits of muscle growth, you can also exercise your balance and stability in ball training, which will improve your overall sports level and help you prevent injuries.
Try these methods when you do sit-ups with fitness balls. Using these methods to exercise with fitness balls can bring us many unexpected benefits. In fact, if you have the strength, you can do sit-ups without fitness balls, so you can also get the benefits of exercise by doing sit-ups with your bare hands.
