This is what you do guys. Get two 10 gallon buckets. Fill one with cold water and LOTS of ice. The other fill with very hot water. Make sure that the hot water isn't going to burn you, but you want it was hot as possible. Stick arms in ice water first for 30 seconds, then put hands in hot water for 3 mins, then back to the cold water for 30 seconds. Do this for 15mins. ALWAYS start and end with the ice water.
