30 Days of LIIT is a month of Low Impact Interval Training: thirty short daily workouts, all standing, none of them jumping, no equipment anywhere. Interval training is one of the most effective ways to build fitness, and LIIT keeps everything that works about it - short bursts of effort, real rest, a rising heart rate - while taking the impact out, so you get the benefits of interval training without landing on anything. Whether you want a joint-friendly way to train, something lighter alongside other work, a program you can do in a small room without disturbing anyone, or you simply like this style of training, it fits.
Every day takes only a few minutes and works the same simple way: short bursts of work with a full minute of rest between them, and you choose how many rounds you do - three, five or seven, and you can change your mind from one day to the next. The days rotate through low impact cardio, leg work, standing hip and balance exercises and arm sessions, so nothing gets hammered two days in a row and the whole body gets its turn every four days. Everything is timed, so there is no counting: you move for a few seconds at a time, as fully as you can, and your version of "fully" is the only one that matters.
By the end you will have trained every day for thirty days without a single jump, and that consistency is the real prize. The heart and lungs get fitter, the legs and hips get stronger and steadier, the shoulders learn to hold themselves up, and the joints are left out of the bill entirely. Finish the month and you will be ready for whatever comes next - and if the answer is another lap of this program at the next level up, that is a perfectly good next.
