That’s an awesome pic btw. I can’t imagine going over a rock now let alone jumping after riding that thing yesterday. I have a ton of learning to do
Nothing replaces seat time. Most new guys sweat the jumps for the first year or so because you won’t be carrying much momentum through the corners so you have to be so hard on the throttle to “make” the jump and that makes the bike react less predictably then it would if you already had your momentum up, and possibly a gear higher then you think you need to be.
Even if you’re going to be more of a trail/off-road guy then a motocross track rat I would suggest studying form/technique of the motocross guys. It will serve well in all situations.
