Great tips, guys. Zandra, you are completely right; the more you move, the more results you will see.
"Diet" is probably one of THE most important factors in successful weight loss. Think of it this way: healthy, BALANCED eating forms the foundation or the baseline of maintaining/achieving your ideal weight, while the fitness and exercise components level off the rest of the excess flubber. Proper nutrition is the anchor, while effective exercise attacks and targets that unsightly bulge. It's a one-two punch against "fat," best used in combination.
I'd recommend alternating cardio and weight training for the amount of time you can devote to it. Start with a moderate amount of weight and simultaneously increase the weight while decreasing your reps. For cardio, I tend to favour intensity over long bouts on the elliptical, treadmill, or track. Try increasing the intensity settings on your machine every 30 seconds until you reach your peak. Maintain for about a minute or so, then decrease to your starting level; maintain for a minute, then repeat. Do this for about 20-25 minutes. You should feel worked out after that.
You've mentioned that money and time are both high on your list of considerations. You don't need to frequent a gym to make it happen; however, it may involve being more creative and/or dedicated to gettin' 'er done. Cardio is the easier part; running can be done nearly anywhere you live. If you have the option, try to pick less-congested areas that offer strips of straight pathway—a long boulevard or street, or even a soccer or football field. To up the intensity, alternate moderate running with sprinting; you will feel this. Be aware that when exercising outdoors, you have to be willing to brave the elements and terrain. If anything, I’d recommend investing in a solid pair of runners or cross-trainers. All other workout gear aside, proper runners are crucial to any physical activity. The switch from running on a treadmill to pavement instantly increases the level of difficulty and stress on your joints; be mindful of this.
As for weight training, if you don't own a set of dumbbells or a barbell with weights, use your own weight as resistance. I’m a big fan of the pushup. When properly performed, the benefits are outstanding. This one move works your shoulders, biceps, triceps, chest, AND abs at once. Other examples of non-equipment resistance training include tricep dips using a chair or other hard, leveled surface, squats, lunges, and pull ups. Also (and you’re going to laugh at this), consider using household objects as resistance equipment. The first year I really broke into training, I had literally no resources except for a pair of sneakers. To add weight to my routine, I used soup cans or laundry detergent bottles for bicep curls and tricep kickbacks. Silly? Maybe, but I actually saw moderate results using these items. It’s what many of you mentioned already: the key to losing weight is to move more, period.
Hope this helps.
Best of luck,
Lee
