Fitness Magazine online has a great article for walking, aiming for 45 minutes at a time, at least 4 days a week (5 is better) that burns 1300 calories / week as well as toning musculature.
It’s amazing how much better walking can make you feel. Tonight I’ll be hitting the gym, walking for 45 minutes at a 6% incline so my calves don’t feel left out, and then tomorrow morning it’ll be Hatha Yoga for 75 minutes at the yoga studio at my local gym. Sunday I’ll be taking off to get some things done around the house and creating my menu for next week (I suppose I’ll walk on Sunday as well, but it’ll be at the grocery store). I’m anticipating at least 2 hours of meal planning, as it’ll be my first rodeo in that respect.
