Is it better to practice hard pulling with your back or your legs?

Whether to practice back or leg is a problem that puzzles many trainers. Strictly speaking, hard pulling is a whole-body action, especially the back thigh, erector spinae and grip strength. If the action is accurate and efficient, it can activate the front thigh, latissimus dorsi and even abdominal muscles, so it is back exercise and lower limb exercise. Then how to arrange it in the training plan is more reasonable. Personally, I prefer to arrange it in lower limb training, and any form of hard pulling is like this. There are several main reasons why I didn't arrange it in the later training. First of all, although hard pulling can be regarded as a good action to improve the overall dimension of the back, it is more of a lower limb-led action, especially the hip extensor, which means that your lower limbs will be greatly challenged in hard pulling training. Then separating the hard pull from the lower limb training and arranging it for other training days is likely to lead to the problem of hard pull before the leg recovers, which will stimulate the leg and affect the next lower limb training. Comparatively speaking, both the traction ability and the recovery of the back are faster than those of the lower limbs, so there is no need to worry about the situation that the back is stimulated and difficult to recover during hard pulling training, which will affect the next back training. Another point is that it is difficult to pull hard and squat. I don't want to face a situation where a training plan is difficult for two days. So I'd rather arrange it on the same day, which is more acceptable psychologically. In addition, hard pulling is not an action that requires frequent training and load-bearing, so I don't have to worry about the situation that I can't pull as hard as before after squatting. More importantly, technical proficiency.
