Keep your contact consistent, making sure that the horses' focus is balanced between your cues and the jump. Sitting deep and encouraging them forward with your legs and seat, only use a whip if you have to. Some riders will carry the whip just for that bit of extra forwardness and impulsion but it's up to you :)
My recomenedation would be to seat back, squeeze your legs, and if needed whip or voice!
Hope it works. Stephanie
Legs on (squeeze your legs), whip , having good contact and heels down ☺️ Hopefully that helped
