45 minutes. 8 rounds. Let’s get Gritty!

LIFT: YOU VS. THE WEIGHTS

In just 2 rounds, we challenge you to go heavy, using kettlebells, medicine balls, and dumbbells for maximum power output. Whether you’re taking Classic Grit, Core Grit or Condition Grit each class will ensure a comprehensive workout that builds muscle strength and endurance.

This type of workout also accelerates your metabolic rate, burning calories not just during the workout but long after you’ve left the gym. The resulting enhanced metabolic function is crucial for your body’s endurance, stamina, and overall health. 

Heavy lifting isn’t just good for the body; it also challenges the mind. It requires focus, determination, and mental toughness to push past your perceived limits, through the physical discomfort, to achieve your lifting goals. With enough consistency, you’ll be building a strong mind along with a strong body as you set your goals even higher.

HIIT: YOU VS. TIME

Our High Intensity Interval Training features plyometrics, stability, and resistance training at our wall station. This active segment demands that you dig deep and push through each set as fast as possible. Expect to do high knees, bicep curls, and more in a high-intensity setting. It’s all about maximizing your calorie burn in a short period, enhancing your cardiovascular health, and even building your cognitive functions. 

HIIT sharpens your mental acuity by enhancing concentration and speeding up your reaction times. Each round requires your full concentration. The rapid decision-making required during these intense intervals translates into better stress management and mental clarity in your daily life. 

PUNCH: YOU VS. THE BAG

Our kickboxing rounds focus on improving your reaction time, precision, and agility as you execute each strike with purpose and power. Many people find that hitting the bag in a controlled environment can be incredibly cathartic – allowing you to jab, hook, and elbow your challenges literally and figuratively. 

Kickboxing is a mental game just as much as a physical one. It enhances your reflexes and reaction times, making you quicker on your feet and more responsive in your everyday life. The full body workout we deliver burns calories, tones muscles, and builds a strong cardiovascular system. All while boosting your self-confidence and your mental toughness to conquer every day with intention.  Check out every way kickboxing can be a major asset to you here. 

WORK: YOU VS. YOURSELF

8 rounds of fast-paced interval training in 45 minutes with brief recovery periods push you to maintain intensity over duration in our classes.  This workout is designed to do more than just  help you build muscle, it also significantly increases your metabolic rate. The brief recovery periods designed into our workouts help teach your body to recover quickly, improving your overall fitness resilience and preparing you for greater challenges—both in and out of the gym.
