Squat exercise in powerlifting is prominent for building lower limb muscles of the body which is
supported on the feet and the knee is bent so that the buttocks rest on the heel. Powerlifting Squat
requires the lifter to squat down until “the top surface of the legs at the hip joint is lower than the top
of the knees”. In powerlifting, the qualifying weight for a squat must be 90 kg or more and the sitting
position must be 90 degrees. When a lifter is practising with 100 kg of weight, it is challenging for him
to focus on his sitting position. Our research focuses on developing and designing an instrument in
such a way performer clears his seating stage which is 90 degrees or more than that with 100 per cent
accuracy. This design aims to address these challenges in an innovative and distinctive that is suitable
for the user. To achieve our goal, we have used economical design materials to achieve a reasonable
price for our design while maintaining a high standard of quality. Also, economical and readily
available manufacturing processes were used to reduce the complexity of manufacturing the device.
The Squat Analyser has to be a wearable product which can be comfortably worn by the user. It has an
adjustable belt to suit the user’s needs. This design can go in for further development later on and be
improved technologically and ergonomically for the user. It helps in strengthening the muscles in the
legs, including the quadric- ceps, calves, and hamstrings.
