Intro

I'm studying judo again after many years. I've created this wiki as a study and reference guide for myself and others that want a concise description of traditional Judo techniques and practice. David's Judo log is a record of my practice and events.

Sensei

Sidharth Seth is the sensei for the Aptos Judo Club. Studied at Kodokan Dojo in Tokyo.

I originally learned with Sensei Noriyasu Kudo (hachidan) at the RPI Judo Club. Cool old article about my old sensei here and on the Kudo Kai site here

You can read additional articles about fitness as well.

Opening/Closing

These are the basics of etiquette when starting practice. More on Judo etiquette here.

These are the basics of etiquette when ending practice.

Stretching

1 set of 10 for each on left then right sides. Used at the beginning of practice, and the end for cool down.

Supplementals

Circuit Training

Repeat 10 times each within 5 minutes with no rest. As you improve, increase to 12, 15, and eventually 25 times each. Once this is perfected, you can increase the difficulty of each element. Alternate with a partner.

  1. Burpees - jump and clap, land in squat, stretch and pushup, return to squat, repeat
  2. Situps - partner holds your feet, keep hands behind neck
  3. Height pushups - place feet on back of partner
  4. Reverse situps - partner holds your feet, keep hands behind neck
  5. Leap frog - jump over partner, turn and shoot back between their legs
  6. Kata Guruma (Half Squats) - hold partner on shoulders fireman style and squat
  7. Side steps - at least 5 steps, touch mat with outside hand, repeat in opposite direction
  8. Side jump - partner crouches face down, stand sideways facing forward, jump over facing in the same direction
  9. Tai Sabaki - partner lays face down, stand facing partner's side, jump and rotate to face partner's other side
  10. Clap pushups

Strengthening

Mix and match these for building strength. Most are practiced with a partner.

Tachi Waza Uchikomi Practice

Practice the following throws 100% with kuzushi (off-balance) and tsukuri (body position) but no kake (throw execution), in sets of 10 both sides.
