Do you ever get an itchy sensation when you start a new cardio regimen or just get out and run one day? It starts as a small itchy sensation on the top of your quad that eventually spreads to your whole thigh and even abdomen. It is annoying and really gets in the way of your workout because all you want to do is stop and scratch, which makes it worse. And it is no surprise that the itchy areas are likely your biggest problem areas. Let me explain why. Inside our bodies are major blood vessels and smaller blood vessels called capillaries. There are millions of capillaries used as passageways for blood through our muscles and bodies. When you start a cardiovascular workout, your heart rate increases and begins to pump harder and increases blood flow. As a result, these capillaries begin to expand to allow greater blood flow to the muscles that are working. As these capillaries begin to expand it causes nearby nerves to send signals to the brain. These signals are new to that area since they have gotten little to no exercise and therefore required little blood flow. Our brain interprets these new signals as the need to itch. Annoying right? But don't worry, as your fitness improves the sensation should dissipate because you are in better shape. So once you start moving, and continue moving with regular cardio workouts you won't have to deal with the dreaded cardio itch. I have experienced this itch ever since junior high. I remember every Friday, it was the dreaded mile day in PE (physical Education). I would be super red and scratched up by the time I finished my mile. It always started with me noticing the fat on my legs literally jiggling and within minutes the fat would start itching. As I got older and fatter, especially in the stomach area, I started getting the glorious itching in my abdomen as well. You can see in this video how the shuffle burpees have my belly fat jiggling and super itchy. [wpvideo jndqxn8u] I recently set aside my heavy weights regimen and started on a cardio regiemen using a workout called T25 and sure enough, my legs and abdomen started itching. And I am not over weight. I just have not done high intensity cardio in a while. But I am not going to stop just because my fat is screaming at me, lol. Instead, I will push harder and grin and bare it. Within a week or so it stops. And the lesson learned is to always incorporate at least two days of intense cardio into my workout regimen. Focus T25 is the perfect 25 minute workout to get that done. Checkout my story if you want to see my whole journey with weight loss.
