Working out with Jen is effective and fun. I very much enjoy the added muscle as well as toning up. Jen loves her job and it shows! She is always prepared as for the work out as well as having an upbeat attitude that makes the time pass quickly. As an busy executive and family man leveraging time is what is most important to me. With Jen I am able to leverage my time by doing the most effective exercises. I learned from Jen that 10 + 10 does not equal 20. 10 + 10 equals fun!
