oh yeah! work on your technique to a point where you know how many steps you're gonna run before you make the jump at the board. Measure your running start distance. Time your approach to the board. Visit the gym 3 times a week working strictly on your butt, hams, quads, and calves. The work out to use are squats. doing 6 sets of at least 15 reps per set. Put these to your practice regimen, and it is a promise that you'll be jumping 11+ inches extra in 2 weeks

There are two things I diod to help that. 1 use the parachute run method. They have small parachutes that you run against that help to improve leg strength. 2nd weighted shoes, really do make you build leg muscles. And most important spend time in the weight room.

You have to alternate days dude.  Try upper body Tuesday Thursday and Saturday(you want those guns pumped for Saturday night). \nStart every workout session with a killer warm up followed by stretching. 20 minutes on the step mill will do it.\nlunges will get your quads. Try taking a spinning class.  Many hotties and a good workout. Follow the guys in the gym they will show you a lot of stuff.  also check on line at Men's Health, they have some good workouts there.

there is a pretty good exercise I do for football. You lay on your back and put your legs in the air(just dangle them). Then you do 30 cruches. Take your time don't rush! Then with your legs still in the air (you keep them up the entire time) you do 30 leg lifts. They are where you but your hands under your but and shoot your legs out straight. Then you with your back down lift your legds (still straight) up and down (thats one)You do it 30 times. Then yes with your legs still in the air you do 30 seconds of bicicles. That when you take your legs in the air and bend them.Then you start pedeling them like you are riding s bike. At the same time you put your hands on your head and do half cruches form side to side. Then 30 more leg lifts. Remember kepp your legs up back down take your time and don't give up. Dont wait in between the different exercises. do it 6 days a week.

A couple of good ways--jump rope, or use bench press bar with moderate amount of weight  on shoulders behind back of head, and go up and down on tip toes to strengthen calf muscles.  Also, running backwards uphill strengthens the calf muscles.
