Did a thrusters tabata session yesterday, spent over two hours making a timer just to find out there were already some in you tube, look for tabata training timer on youtube, mine is the black one with white numbers.
I did it with a set of 5lbs dumbbells, yeah, I know... by the end I was light headed and a little dizzy but that was like 20 minutes after because right after the work out my legs were hurting like hell, pain lasted for so long, I had a "hard pump" on them, it wouldn't go away, couldn't even bend my knee, not to mention the burning in my throat/lungs for breathing so heavy.
