Monday Dec 24th: Normal Schedule

Tuesday Dec 25th (Christmas Day): 12pm class

Wednesday Dec 26th: Normal Schedule

Our classes make strong use of play and fun as applied to fitness.  The program will be based on safe and proven movements within CrossFit’s teaching principles of mechanics, consistency and intensity; athletes are taught sound mechanics for movement, and only when they have shown that they can consistently demonstrate sound movement will intensity be applied to the exercise regimen. Consistently good mechanics translates to physical literacy, enhanced sports performance and fewer sports injuries for kids. Not only that, a vast body of research indicates that exercise is beneficial to cognitive function, which means consistent adherence to the program can have a positive impact on children’s academic achievement.  We will run, jump, skip rope; we throw, squat, and pick things up.  We play games and we learn new skills.  Your child will always learn a new movement, apply that new movement in a work out, play a game, and have fun!

Morning workouts will be CrossFit-inspired, incorporating conditioning, and WOD (workout of the day) that touches on the principles that make CrossFit so popular and effective: constantly varied functional movements performed at a high intensity.
Evening workouts will be lower impact and more restorative. These classes may include team-based fitness games, core work, and/or a restorative stretch at sunset.












Travel is fatal to prejudice, bigotry, and narrow-mindedness, and many of our people need it sorely on these accounts. Broad, wholesome, charitable views of men and women things cannot be acquired by vegetating in one little corner of the earth all one's lifetime.”

Coaching Staff

"Each person holds so much power within themselves that needs to be let out. Sometimes they just need a little nudge, a little direction, a little support, a little coaching, and the greatest things can happen.

Zachariah hodge

Zach was a very athletic child exhibited through his involvement on a swim team throughout middle school and basketball & soccer in high school. Additionally, he played several intramural sports in college. Unfortunately, those activities were derailed when he tore his meniscus playing basketball. After about a year of physical therapy, Zach started running to get himself back into shape. After a decline rapid decline in weight from 10k races, he saw a commercial about CrossFit and decided to "give it a try".

Like most of us Zach'sfirst couple of months were very humbling. He only went in twice a week and definitely cherry picked his workouts. With time he grew to respect, admire, value and love the strength and conditioning program known as CrossFit. It has made me him a better human being, a better trainer, and definitely harder to kill. Zach is an active CrossFit competitor and continues to perform in competitions all over the country.

Charmel Rogers

Charmel is a co-founder of Crossfit Kingsboro.  Ever-curious and seeking new challenges, he discovered CrossFit in 2007 and later that year took a class at Crossfit South Brooklyn and has never been the same. He enjoys Crossfit for the competitive aspect - he has participated in numerous competitions in the tri state area and was a teamathlete in the 2009 Crossfit games for Crossfit South Brooklyn.  What he loves most about CrossFit, though, is the long term health benefits that it elicits.

He believes that fitness and fun go hand in hand and loves to share that message with anyone who will listen. He is a gifted musician with an encyclopedic knowledge of music history. Definitely the person to talk to about your favorite obscure band.

Ashlyn Allen 

As a child Ashlyn was extremely active in all sports as a young child. She tried a piece of every pie from gymnastics to basketball with her longest stint in soccer. After a move to a different state in middle school she never go back in to sports but her athletic interest never left. It took some time to rekindle that flame, however. In high school she could barely run a mile.  In college she started focusing on gaining control of my fitness and creating my own workouts. She found CrossFit after my mom (at the time extremely overweight) invited her to go to a class with her. She was sore for weeks, but inevitably hooked.  As her character began to morph in college and she found her passions she decided to further her education in Public Health. She has a passion for eliminating health disparities, increasing access to food security, and understanding social determinants of health. All of this led to her desire to help people become the best versions of themselves from the inside out.

CrossFit is a strength and conditioning program that delivers fitness that is, by design, broad, general, and inclusive. Combat, survival, sports, and life reward this kind of fitness. 

The CrossFit program is designed for universal scalability making it the perfect fitness application for any committed individual, regardless of experience. We scale load and intensity so our programs can be used for elderly individuals with heart disease or cage fighters one month out from televised bouts.
