OK, let's talk fitness. What I'm about to share is the result of working with personal trainers and many years of research combined with trial and error. I'm not saying that it's the definitive guide, but I hope it helps. In a nutshell:
3500 calories equals one pound. The average adult woman burns somewhere around 1800-2000 calories per day, from just doing normal activities. You can lose weight by either reducing the number of calories you take in, increasing your activity, or both. (I like both.) When you think about the numbers, it makes sense that those "bananas-only" diets which promise you'll drop ten pounds in a week are utter nonsense. You'd have to decrease your caloric consumption by 35,000 calories, which means 5,000 calories per day over a one-week period. Unless you were living at Dunkin Donuts before and then switched to running triathalons in the Alps, creating that kind of deficit is virtually impossible. Instead, aim for losing 2-3 pounds per week.
You can cut your calories by reducing portion sizes and choosing lower calorie options. The portion size reduction is SO easy! Just cut out a third of what you eat. You might feel a little hungry for a day or two, but then you won't even notice. Eat more veggies to fill yourself up. Avoid the empty calories in sweets, alcohol and butter.
'All that said, it isn't just calories in/calories out. Your metabolism plays a role. That explains the person we all know who can eat whatever she wants and never gain a pound. There's a whole science behind the
glycemic index (GI) and how your body metabolizes food, but it's too deep a subject to go into, here. Very simply put, low-GI foods make you feel fuller, longer, resulting in lower calorie consumption.
You have the same number of fat cells that you did when you were a kid, so the object is to shrink them. The first 5-10 pounds that you lose will be mostly water that was trapped in your cells.
So, we covered "calories in." Now let's talk about "calories out" through exercise. The concept behind High Intensity Interval Training (HIIT) (that I mentioned in a previous post) is to get your
target heart rate range up, let it come down and then repeat. The particular activity that you do is not that important, as long as you're exercising at 80-90% of your target heart rate zone on the "up" intervals. It's not just the calories that you burn during the workout that matter; it's the increase in your metabolism afterward that turns your body into a more efficient calorie-burning machine, more like that odious person who can eat whatever she wants to.
Queenie, I don't know if your hip is ready for HIIT intensity on a cross training machine, because the activity is probably weight bearing. A lot of doctors recommend a stationary bike for training after THR because it's easier on the hip and you have a lesser chance of slipping or falling. I'm also unsure about doing squats at this point unless your PT person or doctor OKs them. Squats put a lot of pressure on the lower extremities, and they're easy to do incorrectly. I would pick a HIIT exercise or two and do them with a PT to ensure the correct form, and then you can do them on your own, thereafter.
Here's a typical
Tabata-type HIIT routine: warm up with a combo of light jogging, jumping jacks, forward alternating kicks and side-to-side lunges (not too deep, just a knee bend to get a stretch) for about 4 minutes. You'll feel your heart rate coming up, but you should still be able to hold a conversation without panting. Then, begin your first interval. You can choose 20 seconds of high-intensity activity, such as running in place with high knees, followed by a 10-second rest, repeated 4 times, or if you're on an exercise bike or machine, you can have a longer rest interval. I typically do one minute of high-intensity pedaling, following by 1-2 minutes of slow, easy pedaling. Here's the trick: during the high-intensity phase, go full out! You should be sweating, breathing heavily, and your heart rate should be well up into your high target zone (but not past it). You can check your heart rate during the low-intensity phase to ensure that you're not overdoing it. Be safe, but really push it. Get the lead out.
Then, repeat the interval 3-4 times, and follow it with 2-3 minutes of cooling down (easy jogging or pedaling). Ideally, the whole routine should last between 15-20 minutes, including the warmup and cool-down. That means you're really only doing intervals for 12-15 minutes. Don't do more! It doesn't help. You've probably guessed by now that you'll need a timer. I have a sports band that vibrates on my arm when it's time for the next rest or interval. You can adjust the intervals to different lengths. Or, use hubby with a timer or your kitchen clock.
In addition to the HIIT, consider weight training. Muscle burns more calories than fat, even at rest. That's why adding 20 minutes of basic weight training to your routine a few days per week will help to ramp up your efforts. Don't have weights? Use soup cans! Besides, nobody wants that floppy thing under the upper arm.
Also essential: get enough sleep, drink enough water and avoid skipping meals. Numerous studies have shown that ignoring any one of these three things can really sabotage your fitness efforts.
Measure your results by 1) how great you feel and 2) dress size or how your clothes fit. As we've said, muscle weighs more than fat, so I'd rather be a ripped 165-lb. person than a flabby 150-lb. person.
After reading what I just wrote, I am chomping at the bit to get back to all this as soon as my doctor clears it. Yesterday, I cleaned my house, Swiffered my floors, grocery shopped with the fiance and then went out for an appetizer at the pub. A week ago, I was in the hospital. Amazing! BTW, the fiance has one paw out of the dog house because he showed up with flowers, champagne and jewelry on V-Day, but it's still going to take some time for me to get over the man flu ridiculousness.
Good luck with your efforts and keep in mind a silver lining that I forgot to mention: doing the HIIT exercises really boosts your mood, and the effect lasts. Cheers! -HHH
