It is ok to press the inner thigh by hand in the gym. Personal trainer massages the inner thigh mainly to check the state of thigh muscles. In fitness training, the state of muscles is very important. If you are stiff or tired, it will affect the exercise effect and have the risk of injury. By massaging the inner thigh, the personal trainer can judge whether the muscles are fully relaxed, thus providing us with better fitness guidance. In addition, the personal trainer can also judge the flexibility of our body by massaging the inner thigh, because the muscles and fascia of the inner thigh are close to the pelvis and hip joint, so this action is also needed to judge the flexibility of the body. If our body is not flexible enough, it will affect the stability and range of motion of the hip joint. Personal education can judge the flexibility of our bodies through this action, so as to make a more suitable training plan for us. Therefore, it is a normal fitness skill for the personal trainer to press the inner thigh by hand, but please note that if there is any discomfort or pain, you should tell the personal trainer in time and let them make adjustments.
