If your stance is weak, then chances are no technique is going to be effective no matter how long you train that specific technique.
The key to one-legged training is that we are training balance, strength, and control through a specific range of motion. These are not addressed by standard weight training exercises (leg extensions, leg curls, squats, etc.).
