About Jacob Zemer

I’ve been a performance coach in New York City for 20 years, helping celebrities, athletes and executives get in the best shape of their lives.

My approach to fitness and nutrition is tailored for clients with demanding careers, families and real life priorities. I’ve been featured on CNN, Fox News and various publications for a relatable, no bullshit approach to fitness and nutrition. 

Way before the accolades I was a kid in Portville, New York, pop. 959. My family was poor, and my mom gave birth to me when she was 16. She was a young mother, with no college education, and my biological dad had very little interest in me. Fitness saved my life. At age 14 I started working out at the local YMCA and it gave me a sense of confidence and purpose I had never experienced before.

I love a good time but I was dedicated to the process and Jacob made it sustainable for me.”

My training philosophy is rooted in consistency and progression. I’ve found that the best results come from performing core movements week-over-week, with a focus on proper form, full range of motion, and progressive overload which is gradually increasing weight week-over-week. When progress begins to plateau, we’ll adjust the exercises to keep you moving forward.

The programs I design are both functional and hypertrophy-focused, aiming to enhance strength, mobility, and muscle growth. Most importantly, all workouts are tailored to be pain-free, ensuring a safe and sustainable fitness journey.

All of my programs are designed to accommodate everyone from beginners to advanced trainees with minimal injuries. They emphasize proper form, full range of motion, and progressive strength development week over week.

Whether you’re new to the gym or an experienced weightlifter, these programs are effective because they are built around the principle of progressive overload. As long as you do not have any significant injuries, you’ll find the structure and progression adaptable to your fitness level.

To learn more about progressive overload and why it’s the foundation of my training philosophy, watch my video: Progressive Overload Explained.

Cardio not only supports heart health but also complements your strength training for overall fitness.

You will receive a custom daily step goal while on the program. Besides that, your app will include workshops on cardiovascular activity. If you are able to spend additional time working out, we will give you recommendations for cardio in line with the American Heart Association’s guidelines.
