Does cardio always end this way

I am new to all exercise. I am extra new to cardio. As a recovering fat guy when my body would get close to a target heart rate, I would just stop. This 30 minutes of cardio bullshit is extreme.

It is day 5 of exercise and I promised to not hold back on the truth. Today ended with me face down on the hardwood floor. Sweaty and panting like a fish out of a fishbowl. I had to rewind back the 7 mins I lost trying to find my lungs and redo the cool down stretches

Well until tomorrow,

Your fish outta water
