Northwest Curves, a fitness center designed exclusively for women, provides members with a 30-minute circuit of hydraulic resistance machines designed for an efficient cardio and strength training workout. During the training, attendees can burn up to 500 calories and work each major muscle group to work toward individual fitness goals. An experienced coach is always nearby to teach and motivate participants, and a soundtrack of fun, upbeat music cues participants to move on to the next station. Instead of fiddling with weight stacks and losing momentum, the hydraulic machines use your own body weight and fitness level to create resistance. Each machine uses push-and-pull motions to create toned, lean muscles perfect for crushing a grapefruit without looking like you can.
