OK, so iv put in some sprinting into my workout routine and it is this(roughly)

monday, wed, fri
40m 3x5
60m 2x3
100m 1x5

Every time i run them next next day my knees feel like i got hit by a freakin buss and hurt very bad. I run my sprints in spikes and each one i start from blocks. Anyone know why my knees are taking a beating?

maybe sprinting is too hard on your body.

If thats the case than that sucks a fat one

it could be. bodies have limitations.

It's probably nothing, this is a new routine for you and it shocks your joints especially if you are heavy. Give it a couple of weeks.

Excder,

I've had the same issues in the past, but I think most came from a previous injury. I made a few adjustments to reduce the pain, as in a more thorough warm-up, running surface, even changed my running shoes.

Your training program looks pretty good. Are all of these full-effort sprints? How about rest in between reps/sets?

I'm guessing that your trunning on a track? if so, is the track made from/out of rubber, asphalt or somthing else?-my school tracks asphalt so...yeah...had to ask.

I had knee problems and my/a athletic trainer told me to build up my quads, that helped me.

Does your knee hurt in a specific area.

If nothing else you could do heat and ice.

Hope I was some what helpful.

Our Track is rubber. And like they day after its just kinda hurts when say im laying on my bed to be on my back and straighten out my legs. They knee just hurts when i do that motion. Like right now they are fine and i even did Squats today and other legs.

How about a trampolene workout instead? I really like my Urban Rebounder.

Im stumped.

try running your sprints on different surfaces or/and ice and heat after you run and see if that changes the outcome, and make sure you stretch.

You give a vague description. You say you run with spikes, that is not someone that just started running would where. I guess you have some prior experience with this since you mentioned the injury had happen in the past. First, if you are in the right weight you shouldn't be pounding your knees to much, if you carrying extra weight that might take a toll. Also, once you are done with the routine are you cooling and stretching afterwards and I don't mean a 30 second stretch, I mean a good 5 minute stretch focusing on the muscles that you worked out. If you haven't done that then perhaps that may be the problem. If you do stretch THOROUGHLY then you might to get home and ice NO HEAT the affected area and seek medical attention.

Need anything else please do drop a line.
