Peggy ran a hand over her head and stretched out her abused muscles. She didn't much care for modern exercise machines but the one he was using seemed simple enough to her eyes. An on switch was about all she was willing to handle at the moment and it looked easy enough; she was always a quick learner. Peggy tied her hair back again and stood on one treadmill next to him, raising her eyebrows at the buttons. It didn't take her long to figure it out, actually and she had her science division training. Peggy programmed the machine and began working her legs slowly at first. She gripped the sides of the treadmill, eventually getting the rhythm of the belt underneath her feet in a good motion. "Fascinating machine." She muttered, "Improvement on the older models, of course though unnecessarily complicated." She didn't break sweat when she was running and could easily go five or so miles before it hit her legs.
