Does anyone know what Shawn recommends for cardio workouts, how often and how long?
SP: For the purpose of Transformation, I recommend a twenty minute High Intensity Interval Training (HIIT) session. The 20 minute cardio workout starts with a warm-up of about 3 minutes, then alternating minutes of high intensity with a lower intensity for 15 minutes, followed by a 2 minute cool down (HIIT Tracker). This works well for indoor cycling, elliptical, stair climbers and the like. Take it outside to a track, field or stairs at a local venue. HIIT is certainly not the only way, but this type of training is designed to keep you from cannibalizing the lean muscle you will be building during your strength training sessions. What’s probably most important is that you pick what works in your life, stick to it, and ensure you’re going hard enough. DO NOT try and do it on cardio alone.
