" Regardless of how busy you are, it’s important to set aside a few hours for exercise. If you don’t give yourself that luxury, you will fall into the trap of being too tired to work out. This lack of energy is actually caused by lack of exercise. It’s a perpetual cycle that many people fall into, but the only way to get out of it is to start moving. You may feel that adding a few workouts to your schedule is selfish because you’re leaving your kids at home or in the gym childcare center. Your laundry might go unfolded, or your dishes may stay dirty for an extra hour that evening. Maybe on workout nights, you serve leftovers rather than a meal from scratch. I promise this is not a big deal to anyone but you. Going to the gym is not selfish. Taking that extra time during your week to nurture your body improves your quality of life. There is a huge difference between exercise obsession and healthy exercise. Three hours per week is a far cry from obsession. To be healthy, you should exercise at least three hours per week. "
