I don't see anything for cardio so I will try here. Hope this is the right place.
I never do cardio but tried to start but after four minutes jumping rope I feel like my heart is going to burst. I get a burning sensation in my chest and throat. I had a few tests done and everything came back ok. Could this be I'm just out of "cardio shape". I can't even jog 50yds without stopping to catch my breath. I don't do cardio thing often enough to try and help things. What are your guys suggestions? Also I'm 27. Around 190-200lbs. Pretty good shape. Any help would be great. Thanks guys
