If you're one of those people who struggles to find time to workout, much less time to warm up properly, I can relate. One of the biggest complaints I hear from clients, especially those who have gone through physical therapy to recover from an injury, is that their list of warm up exercises would take them 30-45+ minutes to finish and they just don't have the time to get them all done. So they skip their warm up alltogether even though they know it will likely lead to more pain and injury. So, if you are short on time and can only muster a few minutes to warm up before your run, bike ride or any other form of cardio, here are the most important things NOT to skip.
