You can insist on doing pull-ups every day. (Insist on it every day). Choose a lower bar when you start practicing, change to a higher bar when you can do it for 3-4 times, and finally you can't reach the ground by changing your feet. Do handstands and hold push-ups. Make a strong fist and then loosen it in your spare time every day. Practice as soon as you have time. After three months, you will find that your strength has increased.

Exercise foot strength:

1, squat with weight. Barbells are placed behind the neck and shoulders. Hold the pole with both hands, stand up straight, hold your chest and abdomen, and keep your back muscles tense. Then kneel down until the knees are completely flexed, then stop, straighten your legs and stand up with the contraction force of the quadriceps femoris, so that the quadriceps femoris tightens and stops. Get down again.

2. Stretch your legs in a sitting position. Sitting posture, wear iron shoes on your feet (dumbbells or sandbags can also be tied to your feet), straighten your calves with the contraction force of quadriceps femoris, tighten quadriceps femoris as much as possible, stop for a while, and then put it down for redo. Inhale when the calf is straight, and exhale when the calf is lowered. Thought should focus on quadriceps femoris. Both calves can be straightened at the same time or alternately.

3, prone to bend the calf. Wear iron shoes on the prone stool (dumbbells or sandbags can also be tied to your feet). With the help of the contraction force of the biceps femoris, make both calves bend towards your thighs at the same time, tighten the biceps femoris as much as possible, stop for a while, and then put it down and do it again. Inhale when the calf flexes and exhale when it is lowered. Thought should focus on biceps femoris.
