Heckers' Fitness, Zionsville

Personal trainers Matt and Emily Hecker teach clients how to sculpt and strengthen their bodies using cardio, resistance training, and nutritional plans. The team of trainers—including a former Marine and a professional gymnast—lead one-on-one training sessions and small-group weight training, soothing yoga, or invigorating kettlebell classes .

The kettlebell workout, one of the trainers’ specialties, traces its origins to Russia, where for 350 years the round weight with its sturdy handle has been used to build functional strength and flexibility. At Hecker’s Fitness, teachers lead dedicated, supportive groups of students as they tone their cores and condition their muscles through this time-tested workout.
