Fitness Hiking Classes for Adventurers of All Abilities

“Hike with Mike” provides adults of all ages and abilities guided fitness hikes, fitness training, classes, and excursions throughout the lower New York State / Hudson Valley area. Exploring the great outdoors through rigorous fitness hiking synchronizes mind, body and spirit, fostering health, well-being, socialization, and independence.

Our training sessions combine stamina building and fitness training with the ultimate goal of hiking 4-8 mile trails with roughly 800-1000 feet of vertical at Harriman or Fahnestock State Parks. To accomplish this goal, we start with easier and shorter hikes and build throughout the program. We mix in fitness drills such as upper body (push ups, pull ups, light weights, etc.), lower body (squats, burpees, lunges, etc), core strengthening (sit-ups, planks, super-humans, etc.), and stretching (incorporating classic yoga poses) to prepare the entire body (not just the legs!) to take on our hiking challenges.

In Mike’s other life as a Blue & Gold Officer for the United States Naval Academy, he runs Midshipmen candidates through the Candidate Fitness Assessment. The program consists of six physical and motor fitness events that are designed to measure muscular strength and endurance, cardio-respiratory endurance, power, balance, and agility. We customize these drills to each participant’s abilities (don’t worry, it’s fun!!). We also run a VERY modified version of "The Murph” made famous by the LT Michael Murphy, US Navy SEAL Foundation.

We offer 1:1 and 1:2 personal classes and trainings. All of our classes are completely customized for each participant and open to all individuals regardless of abilities. Participants develop hiking skills and build strength and stamina in each session to achieve independence and the ability to participate in community hikes, adventures, and excursions with bigger groups.
