Every successful judo club must have its own system. KL Judo's holistic system for training competitors consists of several elements:

Tachi-Waza
a) Family of techniques
Judokas must identify the tokui-waza they want to have for standing, and focus on that techniques as well as related techniques that can be done without changing their grip.
b) Four quadrants
Ideally judokas will have techniques in all the four quadrants (front right, front left, back right, back left).
c) Combinations
Techniques done in isolation can work but the chances of them working are higher when they are done as part of  a combination attack (e.g. ouchi-gari into tai-otoshi).
d) Action-Reaction
Techniques done from a static position can work but the chances of them working are again higher when they are done in an action-reaction situation (e.g. push-pull).
e) Counters
It's important not just to know how to throw but how to counter a throw as well.  

Newaza
a) Situational
Newaza techniques can be learned according to classification (e.g. hold-downs, armlocks, strangles, sankaku) but they should be practiced according to situation (uke in turtle position, uke on top, uke on bottom, etc)
b) Defences & escapes
It's important to know how to defend against every newaza attack as well as how to escape once you are trapped.
c) Transitions
Transitions that can be made from standing to groundwork is something that are well established. Transitions from ground to standing is something new that the IJF has allowed (for scoring purposes). Judokas must now know how to throw from this situation.

Grips
a) Strategy
Players must be guided by a gripping strategy that allows them to deny uke a usable grip while allowing them to impose their preferred grip.
b) How to get a grip
There are various ways to secure the grip you want. Players must learn how to do this.
c) How to break a grip
Players must know how to break any usable grip uke is able to secure.

Strategy
a) Shido play
Penalties are part of the game. As such, players must know ways to cause their  opponents to incur penalties when the situation warrants it.
b) Killing time
There are times when players are ahead and want to kill time without incurring penalties to win the match
c) Golden Score play
The way a player fights in Golden Score has to be different than the way they play during regular play. Players must be well-versed with Golden Score play.

Conditioning
a) Anaerobic
The most important form of fitness conditioning for judokas is anaerobic fitness.
b) Judo strength
The concept of "judo strength" is the kind of strength you have in applying judo techniques. It is different from pure weight training strength. Judo strength is achieved by doing lots of judo (drills and randori).
c) Grip strength
Grip strength comes from doing specific gripping drills designed to strengthen the fingers.

Randori
There needs to be a lot of randori, done in four minute segments to mimic the usual time for competition. It is during randori that judokas get to experiment and try out their techniques. A judoka should aim to have an average of eight randoris per session.

Shiai
In the absence of external competitions, judokas should take part in internal competitions at least once a month. During regular training there can also be mock shiai sessions.
