Training For Life

To do a concurrent workout in the gym seems a bit awkward–[for example,] run on the treadmill, then quickly run to the weights machine, and then

quickly run back to the treadmill. Is there a simpler way?

So here are three Quick and Dirty Tips for making high calorie-burning workouts more doable:

1. Don’t Use Cardio Machines. Instead do all of your cardio–such as, jumping jacks, jumps onto a bench or box, step-ups, jump rope, or jogging in place–directly next to the machine or equipment where you do your weightlifting set.
2. Mark Your Spot. Use an easily recognizable towel, hat, shirt or other object to drape over one station while you work at another. Sure, this technically means you’re using two pieces of equipment at a time, but there’s usually enough to go around.
3. Bring the Weights to the Cardio. For your weight lifting, choose exercises that use a dumbbell, barbell, medicine ball or other piece of portable equipment; then set that equipment beside the treadmill or bicycle as you work back and forth

Let’s face it. Big lungs aren’t sexy. You don’t see commercials on TV with big-lunged people traipsing through an exclusive nightclub, and you don’t generally brag about your lung size at parties. But if you have ever gotten out of breath climbing a flight of stairs, become frustrated with your inability to run up a hill during a 5K or marathon, or found yourself constantly sucking oxygen on the treadmill or in the gym, then you know that oxygen capacity is a very important component of fitness. But the benefits don’t stop there, since there’s a direct link between a higher oxygen capacity, and reduced risk of death!

What Is Oxygen Capacity?

Technically, your oxygen capacity is actually defined as the maximum amount of oxygen you can use, and is also known as VO2 max. To keep it comparable among different ranges of fitness, oxygen capacity is defined in milliliters of oxygen per kilogram of body weight per minute–but you may also find it listed at liters per minute. For example, the average male athlete has a VO2 max of 3.5 liters per minute and somewhere close to 50 milliliters per kilogram per minute. Lance Armstrong, who happens to be pretty good at cardiovascular exercise, has an oxygen capacity in the high 80’s. You can measure your own oxygen capacity by going to an exercise physiology lab and getting a VO2 max test, or by approximating with a field test. Examples of common field tests include the Astrand six minute bicycle test and the Queens College step test. Don’t ask me where they get these names. One of my favorites is the one mile jog test.

What Limits Your Oxygen Capacity?

There are two ways that your oxygen capacity can be limited. First, your muscle tissue may not have the chemical ability to actually use the oxygen that it is getting from your lungs and heart. For example, if you have low levels of mitochondria–tiny components of your muscle tissue cells that allow your cells to turn oxygen into energy–this will limit your oxygen capacity.

The second way that oxygen capacity can be limited is due to an inability of your heart or lungs to actually transport the necessary amounts of oxygen to your muscle tissues. For example, your heart may not be able to pump enough blood with each beat–and since blood contains oxygen, this limits oxygen capacity. Or your muscles or lungs may not be able to fill with as much oxygen as your muscles need, which would also limit oxygen capacity.

How to Increase Oxygen Capacity

Now that you know what limits oxygen capacity, it should seem pretty logical how to increase oxygen capacity. You can either improve the ability of your muscles to use oxygen, improve the ability of your heart and lungs to deliver oxygen, or do both!

Although oxygen capacity will naturally decline with age (at the rate of about 1% per year after the age of 25), with proper training, you can elevate your oxygen capacity by 10-20%!

Fortunately, since it’s so crucial for athletes to have a high oxygen capacity, there’s been a lot of research done on how to increase oxygen capacity as quickly as possible. It turns out that performing very hard exercise for 3-5 minutes, separated by complete recovery between each hard effort, is a perfect way to increase oxygen capacity. Ideally, if you’re serious about improving your oxygen capacity, you should do these very hard exercises three or more times in a single workout, and try to do at least two of these type of workouts per week. Of course, this type of workout should sound very similar to something I’ve talked about before: interval training!

A Workout to Increase Oxygen Capacity

So how would this type of oxygen-capacity-improving workout actually be structured? Here’s a sample bicycle workout to increase oxygen capacity:

1. Warm-up 5-10 minutes by pedaling easy.

2. Prepare the body for the oxygen capacity efforts by doing five hard 30 second efforts, each separated by 60 seconds of recovery.

3. Now, on to the good stuff! Perform three to five efforts of three to five minutes of very hard pedaling, with three to five minute of easy pedaling after each effort. Each of the hard pedaling efforts should be at your maximum sustainable pace.

4. Cool-down until you’re breathing easy.

With just a few weeks of this workout, performed twice a week, you may actually find yourself bragging to your friends about your big lungs, getting stopped on the street by complete strangers who want to know your oxygen capacity secrets, or filling out the registration form for the Tour de France. OK…maybe not! But at least you’ll have the confidence that any cardio effort will suddenly become easier, and you’ll burn more calories and have more energy.

Q. We’ve had it drilled into our heads that the oil in fish is healthy for us.  So what does it mean when I see one can of tuna with one gram of fat and another with 20 grams of fat?  By choosing the leaner variety am I losing out on all the health benefits?

A.  It doesn’t sound as if you’re comparing apples to apples. The can of tuna with one gram of fat is probably chunk light tuna in water and the can with 20 grams of fat is probably white tuna in oil–and you’d probably drain the oil off before eating it anyway.

If it’s the healthy omega-3 fats that you’re after, choose white tuna canned in water. White tuna is higher in omega-3s than chunk light tuna. And tuna canned in water retains more of the omega-3 fats than tuna canned in oil.

It seems that when you store the fish in oil, the omega-3 fats are more likely to leach out of the fish and into the surrounding liquid. When you drain the tuna, the omega-3s go down the drain.

Here are 3 Quick and Dirty Tips for skinny people who want better bodies:
Lift heavy weights. Your body will be naturally gifted at cardio and light weights, which means these modes of exercise won’t get you quick results. Instead, perform a full body, heavy weight training routine 3-5 days per week. If you don’t have access to weights, improvise with sandbags, buckets or thick elastic bands. Also, check out the space-saving “Selectorized Dumbbells”.
Eat protein. Skinny people are notorious carbivores and rarely eat enough protein to enhance muscle gain or muscle toning. A skinny person should aim for 0.8-1.0 grams of protein for each pound of body weight,.
Limit cardio. Rather than long, slow cardio sessions, incorporate short and explosive

cardio intervals of 30 seconds to 2 minutes, followed by full recovery periods.
