Outdoor abdominal trainer as a preventative approach to back problems

In the centre of the body, the abdominal muscles are the natural counterpart to the back muscles. If you regularly train both muscle groups with the abdominal trainer fitness machine, you stabilise the entire musculoskeletal system, effectively relieve the spine and prevent possible back problems.

The abdominal trainer can be found in almost all calisthenics parks: This piece of fitness equipment allows ambitious athletes to perform a targeted workout to strengthen their abdominal muscles.

The abdominal trainer should also be part of a fitnessparks in terms of prevention.

For whom is the playfit® Sit-Up Bench suitable?

The abdominal trainer fitness machine is a “must have” for athletes. However, this training device also appeals to less trained people, allowing them to strengthen their core in a beneficial way according to their own performance standards.

The abdominal trainer fitness machine essentially strengthens the abdominal muscles and thus stabilises the lumbar spine.

Trained abdominal muscles are the prerequisite for a strong centre of the body (also known as the core) and therefore a healthy posture. At the same time, the training promotes the body’s strength and vital functions.

Advantages of the abdominal trainer

In addition to its attractive design, the outdoor abdominal trainer is characterised by its impressive functionality. The lying surface made of flat, rounded stainless steel struts with round leg fixation not only offers pleasant lying comfort, but also prevents water from collecting in the rain.

For a targeted workout, 2-3 sessions with 12 – 15 repetitions each are recommended.

Instructions for use

  • Lie on the lying surface with your legs bent. Slowly and purposefully raise your entire upper body towards your knees and lower it again. Keep your arms at the side of your body.
  • Ensure that your head is correctly positioned in line with your spine by keeping your neck straight.
  • Perform the movement in a controlled and even manner, avoiding a hollow back.

Increasing effort and intensity

You can increase your strength by holding your arms crossed in front of your chest. You will need even more strength if you hold your arms at the side of your head during the training session. If possible, keep your elbows pointing outwards.


Can the abdominal trainer for outdoor use only be used to strengthen the abdominal muscles?

With this fitness machine you primarily train the abdominal muscles – both the lateral and the straight muscle groups. Secondarily, you strengthen the hip flexor muscles.

Does the abdominal trainer have a maximum user weight?

The training device is designed and certified for a maximum body weight of 150 kg.

How often should I use the playfit® abdominal trainer per week?

To strengthen your abdominal muscles sufficiently, you should carry out two to three training sessions per week. Make sure you have sufficient regeneration phases between workouts. To allow your body to regenerate and your muscles to grow, you should ideally take a regeneration break of around 48 hours.
