Training often warms up with some ukemi practice- rolling and landing on the ground without getting hurt.
Forward rolls, back rolls, side rolls, & drops in a relaxed and flowing manner.
A chance to both loosen up and work on some core kihon skills.
In taijutsu, one spends a good amount of time just rolling around.
But we can also use ukemi as a way to check for tension in our body and improve the flow (nagare) of our game.
Here is the drill.
Start with a forward roll and practice it in a slow manner for about ten minutes. Whatever is your regular speed, go a bit slower.
Pay attention to your breathing- keep in natural.
After ten minutes of just forward rolls, stop and assess how you are feeling.
Parts of your body sore or tight?
Shoulders and hips?
Using it as a way to see the tension or weak points on your body- followed up by hitting them with some junan taiso.
Ukemi as a kind of martial arts yoga to see how you are moving.
