Here is the first, simple version of one kind of cognitive jumps that you can use for warm up if you want to increase the challenge.
The pattern of jumps is: left leg, right leg, both legs.
Meaning that you should first jump off from both legs over the line and land on left leg, then jump off from left leg over the line and land on right leg and then jump off from right leg over the line and land with both legs. From here you will continue by jumping off from both legs over the line and landing on right leg, then jumping off from right leg over the line and landing on left leg and jumping off from left leg over the line and landing on both legs.
Try to connect all jumps into the flow, without taking pause after landing on both legs.
In second option of the same exercise, you can make same jumps, but instead of jumping sideways, you can jump forward/backwards following the same pattern that is already explained above (left leg, right leg, both legs).
You need to do the jumps first time slowly and then you can increase the speed.
In a few days there will be a next version of these jumps! 🙂
