Breaking a sweat not only cools you down during exercise but also rids your body of the disgusting water that’s just building up inside you. Sweat it out with this Groupon.

Choose from Three Options

• $35 for 10 muay thai, MMA, or Brazilian jujitsu classes (a $250 value)

• $19 for 5 muay thai, MMA, or Brazilian jujitsu classes (a $125 value)

• $39 for one month of kids’ classes for students aged 5–13 (an $85 value)

Instructors teach adults and kids age-appropriate techniques from muay thai, also known as “the science of eight limbs” for its onslaught of punches, kicks, and knee and elbow strikes. Complementing the hard arts of muay thai, Brazilian jujitsu classes focus on the softer arts of takedowns, joint locks, and chokeholds that use your opponent’s momentum and bodyweight against them. See the class schedule here.

Please note that this Groupon is valid at the Newark location only.
