How to cure a pulled hamstring FAST.?

The question is whether you pulled the muscle or only tweaked it. If it is only tweaked then ice it for twenty minutes per hour. It possibly could be ready by Saturday. If you really pulled it forget Saturday. Hamstring injuries are notoriously slow to heal and can take as much as nine months to fully heal. Stretching is not the answer to this problem but strengthening is. As the pain decreases start to work the hamstrings. Since you are going to a gym hopefully they have a prone leg curl. Start out working the non-injured side. Take a light weight and start to work your way up. Get to a weight that you can handle and the key is to be able to hold one strong contraction with the good leg for twenty seconds at the end position. Relax after that and wait thirty seconds and again do that one hold for twenty seconds. After that rest for another thirty seconds and try a light weight with the injured leg. Don't force the leg but see if it can curl a light weight. Get the weight up to the end position and hold it for twenty seconds and relax. Wait thirty seconds and do it again. You should find that the weight is not heavy nor does it bother you to lift it. Go back to the good leg and lift again with the last weight for another twenty seconds. Rest for thirty and repeat. If the injured leg was fine without any problems lift the next weight up in the stack. If that is too much drop down to whatever you could do last and go through the routine again. Over the next few days you will see an improvement in the injured as well as the good leg. Keep testing the injured leg to see if it can lift more but don't ever force it. Use ice on the leg post workout for twenty minutes. Stretch gently at this time.
