Boxing.

Kelly showed you some boxing moves, so you attack Helene with your fists. You throw a hard left she dodges, then a right jab she knocks away. She hits you back with a quick jab, flashing into your face, and this stuns you log enough for her to sock you hard in the gut. You're not prepared for this and almost bend over. Helene steps into you, throwing a barrage of hard punches, ending with a wicked right hook that knocks you down to the mat. You barely manage to scramble away from her, over to the ropes, and pull yourself up to your feet using them. Helene approaches you as you're still groggily hanging on the ropes.
