I have been walking for about two months now on a treadmill..been set at a 15% incline for around 30 minutes a day..sometimes twice a day..I usually have it set at around 4.0-4.2 MPH..I do this with usually no problems. I have been doing this 5-6 days a week..I am a 30 year old male..
Today I was winded..could barely finish 25 minutes..I was tired and having trouble completing it..definitely not comfortable..nothing was hurting me..just did not have the same endurance I usually have..not sure what happened
Usually I come off the treadmill and can jump right into weight training, but I could not do that today-had to take 5 minute break
Any idea why I was so tired all of a sudden today? I didn't think endurance could go down when it came to cardio exercises.
