I tend to stick to half halts, and work with transitions and poles if a horse is excited about faster work. Also try your best to relax, tensing up won't help - I hope everything works out for you!
You could try and use a martin gale or draw reins to keep his head down and pull and realse with the outside rein also try to sit deep and into the saddle
Lower your hands and try to really relax your body especially if you get tense/nervous when he he does this
Lots of lunging with loose side reins or loose draw reins and get him working long and low, also try half hault x
