PUNCH45 Classes

This full body workout uses the fundamentals of boxing to combine cardio, strength and toning into a fun high-intensity fitness experience. This class takes place in a dedicated boxing studio equipped with 12, 100 lbs, heavyboxing bags where you can unleash your inner strength. You will deliver jab, cross, hook and uppercut combinations, working not only your entire body but also your mind... giving you the most empowering workout of your life! Your body will never get used to our Punch45 workouts because they're different every time.


Boxing has a number of advantages. It offers a great cardiovascular workout that will melt away the fat and keep you looking lean. Boxing also involves strength training to tone your muscles without building too much bulk.
PUNCH45 is structured as an interval workout designed to fluctuate your heart rate, creating more of a calorie burn than some traditional forms of exercise, like running.

Benefits of Boxing:

  • Prevent injuries
  • Burn more calories which burns more fat
  • Prevent bone density loss as you get older
  • Improve mental sharpness
  • Relieve stress in a healthy way
  • Increase balance, coordination, reactivity and agility
  • Best of all, boxing is just plain fun

What to expect when you take PUNCH45?

PREP - Start with muscle activation to get core warm and joints prepared (using resistance bands and stretches).

BUILD - Dynamic warmup that includes shadow boxing and heart rate lifting sets using med balls/agility footwork/squats/lunges/jumping jacks.

BURN - Metabolic conditioning portion: use punch combinations on heavy bag to lift your cardio capacity, build strength and tone (3 minute rounds with active rest in between). Your instructor will tell you, show you, and teach you how to execute each move throughout the rounds.

COOL - Ab work to strengthen your core (sit-ups, planks) that will improve your punches, protect your back from injury and help you feel super fit! Followed by 5 minutes of stretching.


PUNCH45 is best for those looking for a full body workout that combines cardio and strength training to tone your muscles, burn fat, and increase your overall stamina and endurance. Boxing is also a great alternative exercise for those bored with standard workout routines or those who thrive on sports or activities. You may find it easier to get in shape with workouts specifically designed to improve your movement, punching, and footwork.
