Do Romanian hard pull (that is, the thigh and calf are pulled about 170 degrees, and other movements remain unchanged). This kind of hard pull is very obvious for training the back of thigh, and its weight will be much lighter than hard pull. This action can be said to be slightly lower than the hard pull, because his legs and hips don't need to be folded much. Just bend slightly, keep your upper body head and torso upright and lean forward.

Auxiliary action 2

Rowing is also a very golden action to train the back. The starting posture of rowing is basically the same as that of hard pull, but the weight of rowing will be much smaller, and rowing can simulate hard pull in the starting posture. Because the weight of rowing boat is small, many people can really control it, not be controlled by weight.

Auxiliary action three

Empty rod hard drawing or small weight hard drawing

In this case, fully simulate the posture of hard pulling with load, control the action well when the load is small, and repeat it many times (more than 20 times). At the beginning, most people may control it well. In the last few times, even if they are empty or light, their muscles can't keep moving, their endurance is not strong, and they will be deformed when they exercise.
