Our L.I.T.T. method allows anyone to reap the benefits of strength training while minimizing risk of injury on the joints (Low Impact Training). Here, we focus on the total amount of time under tension rather than how much weight is being lifted. Staying true to the original 48 minute formula, the 2.0 features 40 second work intervals followed by 20 seconds of rest without the motorless cardio pieces. This workout will tighten and tone your body, fire up your metabolism, and finally smash that stubborn fat.
