SPEED PLAY

In order to run faster it is necessary to…run faster. Elite athletes will tell you that they are able to compete at the highest level only by training at or near maximal capacity. Enter interval training, known alternatively as sprinting, repeats, or my personal favorite, speed play (from the Swedish word “fartlek”). And indeed studies have shown that speed play can benefit every type of athlete, from recreational runners to committed fitness enthusiasts, and in a fraction of the time required by training at a lower intensity. In fact, as shown by a recent study, just fifteen minutes of intense exercise three times a week provides a host of benefits over more casual workouts, from lowering your blood pressure and blood sugar to reducing both body fat and cholesterol. Speed play also increases VO2 max, which measures your body’s maximal ability to take in and use oxygen. VO2 max is not only a measure of fitness: it is also a predictor of lifespan, as research undertaken at the Cooper Institute suggests. Sound like a panacea? With these manifold benefits, speed play just might be.
 
THE TRACK
While puttering around the elliptical chalk-lined polyurethane like a rat in a maze can rate high on the tedium scale, the track brings distinctive advantages. These include a level surface (uneven surfaces can simulate leg-length discrepancies and irritate your iliotibial band) and measured distances, not to mention the absence of cars and the unhealthful noise and exhaust they emit.
 
Finding a track is easy. Most high schools, junior colleges, and colleges have fields open to the public. Parks and recreational centers often offer dirt trails of unconventional distances that bring a cornucopia of sights and sounds. Start with a 10-minute warm-up by jogging around the track a couple times. Then do four sets of 2 laps at 90 percent of maximum heart rate. At this level of intensity, you should be gasping for breath and in no way able to carry on a conversation. If you’re a numbers cruncher, simply subtract your age from 220 and multiply by .9. Follow each sprint with three minutes of light jogging, then finish with a five-minute cool-down.  If training at unvarying distances sounds too monotonous, try descending intervals, 800 meters, 400 meters, 200 meters, 100 meters. A study published in the Journal of Strength and Conditioning Research found that descending intervals increase growth hormone more than running at a fixed distance; this muscle mediator builds strong quads needed for that finishing kick at the end of a race.
 
STAIRS
Climbing stairs is an excellent way to build the large muscles of the lower extremities. This is especially relevant for runners, who are susceptible to weakness in the gluteus muscles. The so-called “dead-butt syndrome,” a result of logging too many miles on flat terrain, can lead to pelvic tilts, gait instability, low back problems, and shooting pains, Dr. Darrin Bright, a sports medicine physician and medical director of the Columbus, Ohio marathon, recently told the New York Times. The glutes play a centrol role in stabilizing the hips and the pelvis in running, and climbing stairs recruits these big muscles. Stair-climbing also encourages high knee lifts, which work wonders for form and keep at bay the marathon shuffle that plagues runners late in a race. Moreover, the intense concentration required by running up a set of stairs improves coordination and is great training for trail runs and obstacle courses. Finally, there is the aesthetic benefit of filling out the contours of an otherwise flat derriere.
 
Wonder whether you should take the stairs one or two at a time? Both have benefits. A Penn State study found that the “double-stair strategy” maximized metabolic cost and strengthened ankle and knee flexors, while burning  an additional 70 to 90 calories per hour. On the other hand, rapidly skipping up each stair targets the slow-twitch fibers of the calves, while a slower lunge-like stride is a great quad and glute blaster. Doing the stairs backwards is a novel approach that improves coordination and emphasizes the hamstring muscles while gathering more than a few curious glances from fellow climbers.
 
HILLS
In the battle for best overall exercise – one that targets both your upper and lower body effectively and in a short amount of time - a convincing case could be made for hill sprints, which some powerlifters regard as being better than squats! Hill sprints combine the benefits of anaerobic exercise with aerobic fitness. They encourage you to run on the balls of your feet with an erect spine, and the increased cadence required by hill sprints and other forms of interval training is an easy home remedy for fixing any gait problems that may otherwise go undetected and lead to injury.
 
Sprinting up hills is also safer than sprinting in the flats, since your speed is limited by the incline, which spares your hamstrings excessive strain. They require the aggressive arm and shoulder action critical for maximal acceleration. Finally, hill sprints are a great way to dramatically increase the caloric expenditure of an exercise that already burns a ton of calories when performed on flat ground.
 
Run as fast as you can up the hill and walk or jog back down. Do a total of four sets and work up to as many as eight. Immediately afterwards your legs should feel like jelly, and the next day you should be sore. In fact, muscle soreness is a great way to gauge the effectiveness of hills and other sprint workouts. Soreness indicates muscle damage and is a sign that your body is releasing cytokines to increase blood flow to the area, and growth factors, which promote the development of new muscle fibers, which means more muscle. But don’t undertake intense workouts on consecutive days. Training sore muscles can tear newly-formed muscle fibers and actually weaken your legs. Following sprint workouts it is best to train at a much slower pace, but resist the temptation to take a rest day. Although resting sore muscles will allow them to heal faster, exercising at low intensity the day after intervals will encourage muscles to become more fibrous and resistant to injury.
 
FARTLEKS
If driving to a remote location to park and run is not for you, fartleks can be done anywhere, including your very own neighborhood. And because they are less structured than traditional sprint workouts, fartleks allow room for improvisation and variation, which helps keep your workout feeling fresh while retaining the benefits of high intensity training. You can casually introduce fartleks into a regular run by picking a landmark (mailbox, driveway, tree) 100 to 500 feet ahead and running to it at full speed, followed by a period of jogging that lasts just as long. Repeat as many times as you can. If you’re training for longer races choose longer distances, and incorporate fartleks into your routine at least once a week.
 
Like other forms of interval training, fartleks push your heart rate towards its maximum and recruit fast-twitch muscle fibers, which are required for speed and anaerobic fitness. This is especially important at the end of your next race when you sprint to the finish – that is, if you like to race, and after playing with speed, you just might. And if you’re a seasoned competitor new to high intensity training, as little as four weeks of the above workouts is all that separates you from your next PR, so start playing today.

  1. Speedwork works! I like doing intervals on the treadmill so I don't have to think about the pace, just try to keep up with the belt. Hillwork, fartleks, and stairs have to be in the regimen too. It's also a good idea to throw in some tempo stuff, like 2 x 5k at a given pace with a given rest interval in between.

    Glad to see you posting regularly again bud!

SOUL CYCLE

This is not a commentary on the latest fitness fad. Because if it were, the little I'd have to say on the subject would be largely derogatory. I simply cannot see see how crouching in a stuffy, dark, cramped room surrounded by sweat-drenched strangers while expending a lot of energy and going nowhere deserves to be called fun, though aficionados tell me it is (fun). I tell these aficionados that if no pain no gain is your thing, discomfort can be had for a lot cheaper than $50 an hour. Try plucking your nose hairs. What we don't do for the sake of beauty. This endurance heir to the Stairmaster and elliptical is all hype. There's a name for the type who likes to run (or otherwise move) in place. It's called a hamster. 

This reminds me of a joke my father likes to tell, about what living with a woman turns a guy into. You go from a wolf to a sheep to a hamster. After nearly 40 years of married life, my dad has added cockroach to the zoological lineage. Which I'm sure …

EVERYTHING'S INTENTIONAL

There is no such thing as screw-ups.

Case in point. My excellent friend Deej comes over to help me beautify the garden. He immediately dives in, crouching down on his knees and weed whacking with his bare hands. Before I can say yay or nay, he proceeds to remove a huge clump of daisy greens from the oblong patch of Earth adjacent to the driveway. The area instantly looks bare. Like the back of Woody Allen's head. Smoothing out the soil and shaking his head Deej mutters to himself "I fucked it up!" over and over again. We try everything. Planting succulents in the daisy's place. Covering it with rocks. But still the area looks barren. And every time you water it the water trickles down onto the sidewalk in the absence of roots to hold it in place. It's getting dark so we go back inside. The next day I return to the spot with a clear perspective and remove all the other daisies, leaving only rose bushes and the succulents that DJ planted, and depositing 10 bags of m…

GRAY MATTERS

I was watching the TV show Naked and Afraid last night as I sometimes do. The show teams together two strangers, a man and a woman, who attempt to survive on their own for a period of 21 days in some remote and isolated region. Some of the locales featured include the Australian Outback, the Amazonian rainforest and the African Savanna. The man may have a military background, or be an adventurist or deep sea fisherman. Sometimes he's an ordinary dude who lives with mom. The woman is a park ranger or extreme fitness enthusiast or "just a mom" herself. Sometimes the couple quarrel, sometimes one or both "tap out" (quit) in a fit of anger or illness. It is satisfying to see them actually make it through the challenge and reach their extraction point. The victors are usually exhausted, emaciated, begrimed and bare ass naked. 

Even more satisfying, at least for me, is the occasional ass shot, snuck in at strategic intervals to boost viewership, of course. It's co…
