For some individuals, increasing the number of push-ups and sit-ups they can do seems impossible. But I have stumbled across a simple and relatively easy technique that anyone can use to increase their strength in any exercise: Grease the groove.
As far as your PT test is concerned, this technique can allow you to possibly double the number of push-ups and sit-ups you can do in one minute in as little as six weeks! And you can do it at work while in uniform.
