Perform a wide-legged push-up.
Begin to lower yourself into a straddle position, bending your elbows to make it easier.
Try to control the descent so that it lasts at least 3 seconds.
When you reach the final planche position with bent elbows, try to hold it for at least 1 second.
You can gradually increase the difficulty by trying to bend less each time.
It is recommended to perform this exercise with push-up or mini parallettes grips, to make it easier to control.
