For today's side deal, $15 gets you a pair of heavy-bag boxing gloves from CKO Kickboxing Brooklyn, a $25 value. These heavy, high-quality gloves work in tandem as an indispensible accessory for a wide variety of workouts and disciplines.

Boxing mitts are required for any class at CKO or, for that matter, anytime you'll be walloping a heavy bag with mitts of fury. The insulating foam protects your five-fingered tools of persuasion, allowing you to release every ounce of aggression into the bag until it spills its sandy insides. Heavy bags are a staple of any cardio-combat discipline, including boxing, kickboxing, Muay Thai, and Krav Maga, so even if you move to a faraway land with no CKO in sight, you'll be able to use the gloves for continued practice. They also look great hanging from rear-view mirrors.

• At CKO Kickboxing, however, the workout is addicting – you just want more – not to mention effective. When I first took my wife, Trisha (also a lifelong fitness buff), to CKO, she also fell in love with the workout – we both saw immediate results and increased energy. – Joe Virga, ProTrainerOnline
