Give skipping a shot.
-very little equipment needed(skipping rope)easy to bring with you.
-warms up wrists, ankles, knees, and to a degree the rest of the body.
-gets heart move'n:scream:
Then stretch out shoulders, arms, legs,chest, and back(upper and lower). Try to hold the stretches for at least 30 seconds each. Take 10-15 minutes to warm up before you ride, and save your-self a couple of hours of gripping and complaining later on in the evening, and the next morning.:eek:
