As a former Yin yoga instructor I know the ligaments, tendons and joints are the "coldest" parts of the body meaning they have the least blood flow. Embrocation pre warms these structures even before you turn the pedals. This is a gentle introduction to embrocation compared to others I have used. I don't notice the heat for hours after a ride which is sometimes uncomfortable. This product also does not have and overpowering smell. This does a good job of warming and protecting those knees. I have also used it on my shoulders before rowing. Do be careful not to get the stuff in your eyes wash your hands thoroughly after applying. The same is true for any other sensitive areas. I put my bib tights on keeping them just below my knees. Chamois cream first and do not keep the jars next to each other please. Then rub a small amount on from just below the knee joint to just slightly above. I might dab a small amount on the outer side of each quad (think IT band) on very cold mornings. Pull up the bibs and go wash your hands. I am a big embrocation fan.
