I put in only 20 minutes in the gym today (not including cardio) with EXCELLENT results. I have broken my workout down to 4 essential exercises. What are they you ask?
That’s it! Try doing as any of those as you can for two circuits. Those are the solid base to my workout. From there I add on at most two specialized exercises (i.e. Bicep Curl, Shoudler Raise, Tricep Ext., etc.). I also add on an ab routine. And even with those ad ons the routine can be done in less than 20 minutes.
Try it out! Let me know how it goes.
