Tips for working out at night ... and not disturbing the neighbor

For some people, busy schedules leave them with little or no time to workout -- except at night before they go to bed. But working out at home after the sun sets can be disturbing for neighbours -- what's the solution? Not working out? I don't think so. Here are some quiet exercise tips from Fitsugar:

• Push-ups, sit-ups, planks and side-planks will tone the core and arms
• Squats and lunges will tone your glutes without make noise
• A yoga DVD is a great way to relax before bedtime
