I write this review to warn others of the pain, guilt and liquid awesome(sweat and watery eyes) that a session with Chris can cause. After 10 minutes I could feel muscles that don’t usually activate, unless I’m running away from something, like a dinosaur. Then I felt guilty for being so squeamish and focusing on my knees being in dirt instead of my plank being perfect. But really who planks for perfection, besides Chris? Finally I realized the 10 minutes were over and I was drenched, out of breath and really angry, at the fat that slowed me down. Overall a great experience, I highly recommend OFA!
