Cross training is done for several reason but the most important is to avoid injury. Your body can only take so much pounding. So here is a little workout for you. Get on the stationary bike and warm up for 10 minutes at 70 % of your max heart rate your resistance is not going to change so have it set so that at 10 min your at your desired heart rate. Now increase your RPM’s so that your heart rate gets up to about 90% MHR for 30-40 sec’s and then decrease the RPM’s back to were you started. Repeat this 5-6 times. As you improve stay at 90 % heart rate for a longer period.
