My favorite client story

It was a typical shift, which means I was cleaning/racking weights, checking on all members to make sure they were doing their workouts correctly, offering critique and even to spot heavy lifters. While working the floor, I noticed a young man working out on the seating “crunch” machine. He turned to me and asked if he was doing it correctly and if he could work his “side abs” with the machine. I told him politely, of course, but in my opinion, that machine is not my favorite way to work the core. And I offered to show him a few other workouts that might get him better results.

We walked to the stretching mat and I demonstrated a few core workouts and then watched as he tried to copy what I showed him. He loved them. That’s when he asked, “How can I get a six-pack?” the favorite goal of most men. I laughed and explained that a six-pack comes with working out the core and losing body fat… the muscles are there; they just need to be exposed. I offered a free season and an FMS (Functional Movement Screen).

During the screening I found that his core was a little weak, as well as his chest. I asked if he could do a pull-up, to which he said he couldn’t. He also had an issue with his hip flexors. I had him do a few more moves to find out where the hip issue was coming from and discovered it was his ankles that were the real weak link. It turned out he used to play soccer and had hurt his ankles a few times.

We met two days later for his free workout. I had designed a simple workout for him, focusing on his strengths but also building up on his weaknesses. We did a lot of core engaged workouts that focused on either upper or lower body. My goal was to work the whole body. When we were done, he was happy but felt that we didn’t do any ab workouts. I laughed with him and asked him if he could do one thing for me to close out the session. I asked if he could do a pull-up for me. Understand, that I never have anyone do anything that they might fail at or embarrass themselves by. He laughed and said he couldn’t and didn’t want to. I demonstrated the proper way to do a pull-up and how to engage the lats and core and then I asked again if he would try to do just one. Reluctantly, he tried to do one and then looked at me with surprise. He was able to do two pull-ups. Something he had never done before.

I did not assume he would be able to afford personal training, but I offered him a 3 days a week regiment anyway, that consisted of two days with me and one on his own with workouts I designed for him. He asked me how long he would have to train before he reached his goal. I gave him a reasonable timeline of three months, trying not to sugarcoat it. But, then I did tell him the one truth I tell all my clients. If you train with me, I will teach you. I want you to be able to do this on your own. He decided to get 12 sessions with me, and we did the 2 days a week with a third I called homework.

I’m proud to say that after the 12 sessions my client dropped 4% body fat and started to see results. But more importantly, his core became so strong that he was able to do 10 pull-ups. He purchased another 6 sessions, wanting to do 1 session with me a week and then doing 2 on his own. We trained for four months total and I am proud to say he now has his six-pack and can do 20 pull-ups.

My favorite exercise

Pallof Press. A simple yet affective workout. The pallof press is an anti-rotation exercise targets the core. You will feel it in your obliques and even your butt. I love it.
