Running with heavy legs like lead or eight causes

 Running with heavy legs like lead or eight causes

Running training, heavy legs do not start, is a very frustrating thing for runners, feeling strong but unable to work out, like the legs poured with lead. So, what causes this to happen?

Excessive Strength Training Intensity

Strength training helps runners increase muscle mass, improve running efficiency and reduce injury risk. However, if the strength training is too much or too intense, especially the strength training of lower limbs, the legs will feel very tired. Even if the upper limbs are full of strength, after all, running depends on both legs, and you will feel unable to move your legs when running. Normally, strength training should be done once or twice a week.

Ignore stretching after running

Stretching after running can relieve muscle tension and soreness. If todays running does not stretch, but directly rest, then the muscles will not be well repaired, affecting the next run, one of the effects is heavy legs.


If runners frequently feel heavy legs, it may be due to overtraining. Overtraining means that the body is under too much pressure, which will lead to increased risk of injury, continued decline in running performance, mental fatigue and so on. At this point, runners need to arrange for a thorough rest, and then start training after recovery.

Running shoes are not suitable

If the running shoes are too heavy, they will increase the burden on both legs. After running for a period of time, they will make both legs feel very tired. If the running shoes are too light to provide sufficient support for the feet, the impact on both feet will increase, which makes the leg muscles more fatigued and feeble.

Running incorrectly

When the runners running position is incorrect, his body will bear extra pressure. As running progresses, fatigue speeds up. One of the most obvious signs is the heavy legs and difficulty in striding.

Gain weight

Even if the runners insist on running training, their weight may increase due to other factors such as diet. Every pound of weight increases the pressure on the body during running. Because the legs are close to the ground, the additional impact will directly affect the legs and increase fatigue.

Low Carbon Water Diet

Some runners adopt a low-carbon diet strategy in order to lose weight. Once the amount of training is large, the bodys energy will be insufficient, it is difficult to maintain high intensity and long-term training, the body, especially the legs feel particularly tired, which is due to the lack of energy.

iron deficiency

Muscles need blood to transport oxygen to maintain their state of motion, and blood to transport oxygen can not be separated from the participation of iron. If the iron deficiency of runners is more obvious, the muscle will not get enough oxygen, it will not be able to maintain the normal state of work, the fatigue of both legs will be very obvious.
