500 is too many, you are not increasing the muscle enough for the hops you are looking for. Read website below for details on your vertical and what can be done.

Well I have played basketball all my life, organized.  Coaches usually have me do calf raises with really heavy weights.  You will know if it is working because for the next week your calf muscles will be really sore.

Strengthen your glutes and do jumping exercises.  Do 3 sets of 10 jumps where you try to reach something.  The next day try to target a few inches higher, so and so on.  Glutes, Glutes and more Glutes.  hip extensions, squats, leg press, lunges, the glute machine if your local gym has one.  There are tons.  Try to target the different glutes muscles as well.  Gluteus maximus, gluteus medius and minimus.  Ask a personal trainer.

Get enough weight to where you can only lift it about 10-12 reps.  Then wait a while, drink some water and do another set.  Do three sets of this about 3-4 times a week.

You could do calf rasies with just your body weight or holding free weights. Look at the very bottom of this page...\n\nhttp://www.thetrainingstationinc.com/freeweightexercises.html

hold on with your hands and put your legs up... four series of 15 or 20 times. Or lay down face up and raise your legas and put them down slow. the same repetitions.

Lots of cardio (4 days a week at least 45 minutes, shoot for higher), reduce your total calories, and perform step up lunges for 22-25 reps maybe higher. avoid using any heavy weights since your not trying to create a large muscular butt.

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

You are improving your cardiovascular system (heart, blood pressure etc.).  It is strengthening your legs.  150 per minute should be sufficient.  It depends on your age and general condition though.\n\nAs to once every two days, you can cycle every day if you want, you don't have to take a day off.  You probably want to vary your routine though by doing some other exercises.  Even basis ones like push-ups and sit-ups.\n\nHave fun.

inner thighs:  leg lifts: stand with feet together, bend knee slightly and lift leg, then rotate toward other leg, like your right foot would be kinda in front of your left shin, if doing right leg lifts.  do 15 - 20  with each leg several times each day.  ALSO, lie on your side on the floor, lift the "top" leg up high slowly then lower slowly. repeat repeat repeat with each leg.\n*** lifitng leg away from the body - like in a jumping jack - works the outer thigh muscles\n\nstomach stay flat:  practice keeping those muscles pulled in!

Should be one day of rest in between to give your muscles a day to heal and tone up.  Congradulation on doing them...its more than most do!

Stand on a step on the balls of your feet and your heels hanging over.  Hold on to the handrail for support. Let your heels drop down slowly then lift them up and stand on your toes as high as you can then slowly let your heels down again..  Repeat 15 times, rest for a minute or two, repeat and rest again.  Do two sets a couple of times every day and increase to three or more sets.  Make sure you've had lots to drink so you don't get leg cramps.  And remember to stretch too.  :o)

Pushup are good.  Also tricep dips.  Get some dumbells for bicep curls, tricep overhead raises, and such.  Do your upper body workout every other day for best results.

I feel that they do.  After wearing heels for a few days my calf muscles seem much more defined, but I'm not sure that it is worth it because it hurts my feet so badly.  If you would like to tone your calf muscles you could stand on a ledge (i.e. a stair) on your tippy toes.  Slowly lower your feet so that your heels go a little bit below the ledge, then go back to your tippy toes.  Repeat for 3 sets of 25.
