I was faced with a dilemma yesterday. Eat the whole delicious Whitman sampler my wife brought home from work or half of it? Wait, you aren't supposed to know about that part.   My real dilemma was what I should do for a workout in the 10 spare minutes I had yesterday. My solution was Tabatas.   Have you ever heard of them? They sound delicious don't they? They are not so tasty, they are actually very challenging.   Tabatas are an exercise protocol discovered by a Japanese speed skating coach. He found a way to get his athletes in better shape in a very short period of time.   To do Tabatas you do an exercise as hard as you can for 20 seconds, rest 10 seconds, and repeat this for 8 total round. Doesn't sound like much on paper, but this rest periods seem like they get shorter and shorter.   I would recommend you purchase a GymBoss or download the GymBoss app. The GymBoss will beep when it is time to rest and then again when it is time to go. This way you can maximize your efforts and not have to constantly look at your watch. The GymBoss app, has a built in Tabata timer as well.   In case you are curious, I chose bodyweight squats for the first round and then pushups for the next round. Another little tip for you, I don't recommend trying to sign any important paperwork right after you complete a round of Tabata pushups. Just take my word for it, bad times.
