What the shit
Classical application of traditional Shaolin training methodology. It basically presents exactly what you did here in the 72 skills of Shaolin. Rock on.
The following is a passage directly from “Training Methods of the 72 Arts of Shaolin” by Jin Jing Zhong. A work that you might want to look up for inspiration as this methodology seems to align nicely with you own:
“At the first stage loads of iron or sand must be tightly bound around the body, but their weight should not be great. Dig out in the ground a pit, one CHI (0.33 m) deep, and with such a diameter that two men could freely stand in it. The trainee stands in the center of the pit and executes high jumps, trying to jump out of the pit at his own choosing. Do that exercise many times in succession. At first the pit is not deep and the loads with iron chips are light, it is quite simple to make jumps out of the pit. Then, it will be necessary to make the pit deeper so that you could not jump out of the pit but could go out of the pit by raising your leg. After that, deepen the pit by one CUN (3.33 cm) in each 10 days or half a month and increase the weight by one LIAN (0.05 kg). Deepen the pit gradually and increase the weight, trying to do jumps easily and freely.
As a result of it the depth of the pit will reach three CHIs (about 1 meter). It will be substantially more difficult to do the exercise now. Therefore, if you earlier deepened the pit with an interval of 10 days to half a month, now you have to increase the interval to half a month or 20 days. Continue to increase the weight and train yourself as before. Over time the pit will be 5 CHIs (about 1.7 m) deep. After that, it will be necessary to continue training and increase the depth of the pit from 5 to 7 CHIs (about 2.3 m) and from 7 CHIs to 1 ZHANG (3.3 m). When the depth of the pit reaches 1 ZHANG and the weight of the loads 5 or 7 JINs (2.5-3.5 kg) and jumping out of the pit is done easily and freely, the training has reached its aim. Take off the loads in that case and increase the depth of the pit to 2 ZHANGs (about 6.6 m), train yourself in jumping out of the pit until you can do it easily and freely. Please note that after you overcame the depth of one ZHANG with the loads, it is necessary to take off the loads and increase at once the depth of the pit as much as twice.”
Didnt know that. Thank you
