Go see your Doctor!  You could prevent a very painful knee replacement when you are older.

Being prone to Detractions of teh Patella myself, the only real way to strengthen laterally the knee is to strengthen all leg muscles equally.  I have overly strong quads and am very lacking in the hamstring dept.  Lunges and lunges done to the side are good.  Just remember to always center your movement on the axis your foot is moving.  That way yu will not put lateral stress on your knee, but still strengthen those muscles.

You can try cross-training with biking to strengthen your quads and hamstrings.  That might help with your knee issues.  Also make sure that you are wearing good shoes and the right type for your feet.  I tend to get some pain when my shoes are wearing out.\n\nDon't forget RICE for pain--rest, ice, compression, and elevate.

Do squats, lunges, biking is good too. All of the exercises that work on your thighs because it's the most important muscle while you're playing volleyball

The crunching in your knee is due to damage, however surgery may not be the best option.  Rehabing your knee by strenghtne the muscles in your calves and quadricepts will help with that situation.  These types of excerices are alos the rehab you would undergo if you did have knee surgery.  Work thsoe muscles to strenghten that knee joint.

sit ups with legs bent at knees left elbow to right knee and right to left.\nAlso roll legs over to left and try to do sit up and then reverse it.\nDON'T DO ANY OF THESE UNTIL YOU CHECK WITH A QUALIFIED TRAINER FIRST I'm not one

leglifts.  lie down on the floor and put your hands under your butt or tailbone so it won't hurt.  lift your legs about six inches off the floor and hold as long as you can!!  it's really hard.

the hardest ab exercises are the ones that involve your legs.  Lay down on your back all stretched out and without bending your knees lift your legs to a 45 degree slowly and down.  Do this 100 times and you'll feel the burn! :-)

Well, I'm recovering from a broken kneecap. My Doctor told me to lay on my back on the floor.\nDraw my one knee up so it points to the ceiling while the foot is flat on the floor. Keep it there.\nThe other knee? Keeping your leg straight, lift that leg about 10 inches off the ground & hold for 10 seconds. Do 100 daily. This strengthens the knee.

Leg lifts and squats.  Stand up and put your hands on steady surface, then lift one leg behind you, knee slightly bent, and lift as high behind you as you can. do ten of those, then switch legs.\n \nsquats are self explanatory. legs slightly less than shoulder width apart, keep your back straight and lower yourself down, then back up. do ten, take a break, then do more.  \n\nRunning of course is always good for the glutes, but its good for a little bit of everything too.

Any box will do... You can try to find those step arobics steps which can add layers to.\n\nYou can use stairs as well. There are many plyomertic exercises, not just jumping off of a box and jumping back up. Do a web search and you'll find TONS of exercises.\n\nI use to do a lot of plyo, but my knees are shot after dunking and playing for over 15 years. Ice them knees dude!

Good sneakers and a well cushioned treadmill will reduce the impact on your knees.  Using the incline should be fine--it's usually the downhill running that is harder on your knees.  Obviously, stop running or walking if you experience any pain.  Consult a sports doctor if your pain is preventing you from running or walking.

put more rotation in your hips and more "push off" from back leg.  If you can rotate hips and push off at same time you wont drop knee.

unless the cracking is painful, it is not unusual or dangerous for your knees to "crack".\n\nLunges are excellent for strengthening the muscles around the knee joint. Make sure that you are not leaning over the knee, that the knee is right above the foot during the lunge and that you maintain a straight upright movement.\n\nDo not do hamstring excercises that will pull on the knee joint if you have problems with your knee. \n\nelipticals are good for running on with minimal knee and ankle stress. \n\nyou can also get large elastic bands...stand in them, and step out to the side pulling on the bands, then back in. Don't pull harder than is comfortable, this will help increase the stablization of the knee.\n\nLaying on your back you can pull your knee to your chest, and then extend it, locking your knee holding the leg just over the ground..repeating, this will also help strengthen the muscles around the knee with minimal weight on it.\n\nAlways is good to speak with a doctor or physical therapist if you have concerns.

At 15 years old you are still growing. The weight will go away eventually, that is, if you dont eat unhealthy and get a little bit of exercise. I know that an elliptical trainer machine is what doctors recommend for people with bad knees. Maybe get informed about that machine, and maybe you will feel a lot better about yourself.\n\nThis is information about elliptical trainer machines\nhttp://en.wikipedia.org/wiki/Eliptical_machine\n\n"An elliptical trainer is a stationary exercise equipment used to simulate walking or running without causing pressure to the joints"\n\nAlso, regular cardiovascular exercise reduces body fat. Wallking is great cardio! Cardio for at least 30 minutes per day will definitely help u lose a few pounds.
