I bought the P90X3 workout program a couple of weeks ago. As a registered dietitian and certified personal trainer, I pride myself in staying healthy and fit. I knew the P90X programs are tough but effective as my step son got in super shape a couple of years ago with P90X. So, I am almost through the second week and Yes, the work-outs are challenging, but I love the variety. I especially like how easy these are to fit into my busy schedule as they’re only 30 minutes!
