It's not necessary to learn Taijutsu techniques. Using Taijutsu techniques like "Great Leaf Whirlwind" is unnecessary, because you can just say "I hit you with a clockwise whirlwind kick" instead, and not use up one of your three jutsus per turn.
Taijutsu is limited only to your imagination. Consider your character to have no physical limitations: you are as flexible and as acrobatic as you want. Your attacks - your punches, your flips, and the way you use them - are only limited to your imagination.
For instance, attack me.
