The dips test is a strength test for your upper body. The test can be done using your own bodyweight and a bench.
Dips: Triceps and chest muscles
Dips primarily train your triceps and part of your chest muscles. Dips are performed with a bench and your feet on the ground. This way of performing the exercise is the easiest and puts the least strain on your muscles and tendons. A more difficult version could involve performing the dips on an elevated support with your legs suspended in the air. It is recommended to first practice the exercises for a period to allow your body to become used to how it is done and to the strain.
