Here is the basic workout that I use to start new clients. It consists of pushups, crunches, bridge, prone cobra, plank and squats. Strive to build up to 4 sets of 12 reps, back to back, with no breaks. This will prepare your core and overall body for more intense workouts. You will also increase your cardio capacity for preparation to do Tabata drills by not taking any breaks in between sets. This is a simple workout that can be used by anyone, anywhere, regardless of your fitness level. If any of the exercises are too much or too hard to start with, use the modifed pushup, plank and shallow squats until you are more conditioned. In the videos below, I demonstrate a couple of reps for each exercise. When in doubt, stick to the basics and you can't go wrong.
