1. Incorrect posture and movements: The correct dumbbell rowing movement needs to keep the back straight and the arms and legs slightly bent, which can reduce the pressure on the elbows and knees. If you shrug your shoulders, arch your back or expand your elbows during practice, you may not be able to fully contract your back muscles, resulting in no feeling in your back.
2. Excessive arm strength: In dumbbell rowing, many people may unconsciously exert their strength with their arms instead of making full use of their back muscles. If the arm is too hard, the back may not fully feel the effect of training.
3. Incorrect weight and frequency: If the dumbbell is too heavy or too many times, it may lead to triceps fatigue, but the back can not be fully trained.
4. Lack of rest and recovery: If muscles are not given enough rest and recovery time after training, muscles may not fully feel the effect of training.
In order to better exercise the back, you can try to adjust the following actions:
1. Be sure to keep the correct posture when practicing, and don't shrug your shoulders, hunch your back or bend your elbows outward.
2. Try to feel the stress on the back muscles, especially when the dumbbell is pulled back, and feel the contraction of the back muscles.
3. Adjust the weight and exercise of dumbbells properly to avoid triceps fatigue.
4. Give the muscles enough rest time after practice to facilitate muscle recovery.
If you still feel no feeling in your back after adjusting your movements, I suggest you find a professional coach or take a video to check, determine the problem, and get correction and guidance.
