Reformer? Megaformer? To be clear, the two are very different workouts, though both look similar in terms of their carriage and springs for resistance. Reformer pilates is a total body conditioning workout. Strengthen your core and improve on your overall strength, posture, flexibility and balance. The latter is a Lagree Fitness method workout specifically designed to strengthen, tighten, and tone the body. The group training exercises or private training sessions in-studio in New York emphasize on cardio, strength, balance and flexibility at once, as used by Kim Kardashian and Michelle Obama - expect more standing and planking positions. Toned arms, anyone?
