Childhood trauma, but make it a fitness goal.

I think this one has been 20 years in the making.

In this job, clients usually fall into one of two categories: the ones you pour into, and the ones who somehow pour right back into you. Both are meaningful, but every once in a while you get client’s that leave you more energized, more grateful, and happier than when they walked in the door.

Emily and Elee are that for me. Two gals that I paired up and quickly became friends, and whose sessions together became one of the brightest parts of my week.

Emily is off to a new state and new adventures and while we’re so happy for her, the gym truly won’t be the same without our little yapper 🤍

Your core training needs progression, too.

I know I s**t on things like bird-dogs and deadbugs a lot. The more nuanced version of this is that they have their place. When I train beginners, or women who are newly postpartum I use these lower level drills too.

The problem I have with these movements is when someone has been training for 6+ months and their training hasn’t progressed beyond that.

To me, they are a drill, not training. They should be use to solve biomechanical issues with the goal being to get to true training that drives adaptation as quickly as possible.

When I think about my own core training, I am trying to find movements that I can actually take to failure. Ideally in less than 10 reps. Today that was:

• Dragon flags (realistically only 1-2 reps but single leg I can get like 6)
• Side Plank Hips Dips (need some load here to make them hard enough)
• Hanging leg or knee raises (pretty cooked after 6-8)
• Ab wheel rollouts (probably need to progress those soon).

Just a reminder that core training isn’t special and progressive overload applies here too.

Girls, we are killing it.

In education, in the boardroom and at home. The gym is the final frontier. The one place where I don’t think we have collectively exceeded men quite yet. There is always going to be a biological disparity when it comes to things like maximal strength, power and speed...but we need to train intelligently. Ditch the b***y bands. Don’t let the boys think we’re dumb.

*Thank you to all of the guys who have taught me everything I know. I’m the trainer and athlete I am because of a lot of male coaches and mentorship 🫶🏼
