Have you heard of Tabata? Good god this is a workout!
Tabata is a high-intensity interval training that builds endurance and strength quickly!
The concept is simple, go all out for 20 seconds, rest for 10 seconds, repeat the pattern until you pass out (just kidding, kinda). Sounds easy and doable.
As I was eager to try Tabata, I hit YouTube and came across this energetic, "fun" hip hop video by Keaira LaShae. The music is pumping (Miss LaShae's), she has a great attitude and doesn't sugar coat that what you are doing is tough and offers modified moves. I made it through and then collapsed in a pool of sweat. But I did it!
