Last night I thought I'd try some tabata DB thrusters. I used 20lb dumbells, and got a score of 7, total reps 61.
By the end of the last interval I was stuffed. Collapsed in a pool of sweat, lungs heaving, shoulders and legs burning. No more than 15 minutes later, my breathing was back to normal, as far as I could tell, and my heart rate wasn't all that elevated. My shoulders and legs still burned though.
Should I have gone for a lighter weight to get more reps done for a higher aerobic demand? Am I cheating myself on tabatas somehow? Can my metabolism be elevated without a significant increase in breathing/heart rate?
