KING OF THE NORTHNUTRITION AND FITNESS
King of the North Nutrition and Fitness is the coaching practice of Mark Chertok, a NASM-certified personal trainer in New Hampshire's Lakes Region.
Mark offers 1:1 online coaching ($149/month) that pairs custom strength training with practical nutrition coaching — plus jump rope training and a free 4-week Jump Rope Jumpstart program for beginners. Train from home or your gym, with a plan that adjusts to your life.
One coach, one plan, built around your real schedule. Your coaching pairs custom strength training with practical nutrition coaching — no cookie-cutter programs, no meal plans you'll quit by Friday. The plan adjusts as your life does, and you train from home or your gym, wherever you actually train.
Serving the Lakes Region and all of New Hampshire, with online coaching available anywhere.
Not ready for coaching? Start here. The Jump Rope Jumpstart is a free 4-week beginner program that builds real conditioning and coordination with nothing but a rope — the same training Mark uses himself, broken down step by step for day one.
Free means free — download it, run it, and see how the coaching style feels before you ever pay a dollar.
Training is half the rebuild — food is the other half. Nutrition coaching here is practical, not precious: real meals built around protein, your schedule, and food you'll actually eat, adjusted week to week as the training load changes.
It's the same approach behind the description of this practice: designed for real people with real schedules.
His approach comes from his own rebuild: a decade sober, built back through fitness, and designed for real people with real schedules.
Mark Chertok is a NASM-certified personal trainer based in New Hampshire's Lakes Region. He coaches the way he rebuilt himself — strength training, honest nutrition, and conditioning work like jump rope that fits into a real day.
