The product is exclusively designed for working out the hip flexors and abdominal muscles. With the legs and the back suitably positioned in opposite to the support pads in a sitting position, the exercise can be done by the help of the product. The shoulders are taken near to the knees when the flexible trunk is forwarded. The workload adjustment as per the requirement of each user is facilitated by the resistance offered by the weight stack of the product. By the use of hip flexors the device allows enhanced abdominal muscles functioning. The fundamental design of the product is based on the biomechanical research done to develop Biostrength®. Without doing any adjustments, the product provides the user to gain total stability.
