Your tech gadget can tell you how hard, fast or far you're going during a workout with the precision of
a drill sergeant, so why would you ever sweat without it? Because science says there's value in flying
solo sometimes and learning to sense your intensity and training capacity. "We already know a lot about
our bodies, thanks to fitness tech," says Greg McMillan, an exercise physiologist and the founder of
McMillan Running online coaching. "When you understand the link between how you feel and how you perform
on top of that, you'll always be able to get the most out of your body."
Take the talk test, not the tech test.
Listening to your body's signals is legit: Research from the University of Wisconsin–LaCrosse confirms
that the old-school talk test is an accurate gauge of your effort during cardio. Go at a pace at which
you can speak only in choppy sentences and you're in the moderate zone, or 50 to 65 percent of your
maximum effort. (If you can speak in full sentences, you're below it; if you're breathless, you're above
it.) Also, asking yourself a simple "How do I feel?" can better reflect how you're responding to training
than an objective measure, such as heart rate, according to a review of studies in the British Journal of
Sports Medicine. Tapping into the subjective—your breath and how tired your muscles are—helps you track
progress and determine where you're leveling off, so you know when to push your boundaries.
Tune in to focus your efforts.
The problem is, many people exercise in a dissociative state, intentionally distracting themselves so
they can ignore the discomfort and hang on until the end of the session, says Jo Zimmerman, a kinesiology
lecturer at the University of Maryland. We've all been guilty of it, cranking a playlist to forget how heavy
your legs feel during a third set of squats or in the homestretch of a long run. But it can be smarter to
enter an associative state; that is, one in which you listen to your body so you're better able to focus
all your effort on powering through a workout or backing off a bit if needed, Zimmerman says. Getting into
the associative zone boils down to two things, McMillan notes: maintaining a sense of your effort level and
deciding how you dish out your energy across a workout. "No objective measure can tap into how much effort
is actually available to us on any given day," he says. "So checking in with your body will help you evaluate
how best to distribute it."
Feel out your run instead of timing it.
Ditch your device and stick to a go-to route so you know your usual pace for that distance, and try to run
it in the same or a faster time. Because you're going by feel, a clock or a GPS won't dictate your pace, and
you may actually blow by your past marks, McMillan says. Think about the quality of the run, he adds. Maintain
a steady stride. Depending on your intensity, your breathing should range from conversational to moderate huffing
and puffing, but you should never feel as if you can't get a few words out. If your breathing gets out of control
or your pace is erratic, your body is telling you it's beat and that it's time to pull back on your speed a bit.
Let your breath be your coach for interval workouts.
Listen to your breath: During the pushes, you shouldn't be able to speak more than one or two words, and your
tempo will definitely start to taper toward the end. (If it doesn't, go harder!) But it's the recovery interval
that really matters here, McMillan emphasizes, because recovering quickly allows you to perform at a higher level
on the next all-out set. Your breathing should return to a conversational state, but not at a totally relaxed level.
Give the heart rate test a try: Lightly press your index and middle fingers on the inside of the opposite wrist,
count the heartbeats you feel in 15 seconds, and multiply them by four to get your beats per minute (bpm). To get
the most out of your body, you want your heart rate to return to 120 to 140 bpm before starting your next interval,
McMillan says. The result? You'll be able to kick your speed up a notch, making each sprint set ultra-effective.
Find your natural strength threshold.
If you're used to doing your circuits strapped to a heart rate monitor, examining how your breath sounds and muscles
feel will help you find your body's natural strength threshold, so you can then push it. Your muscles should feel
engaged and capable, and your breathing should return to a somewhat relaxed rate while you rest between sets. But
during lifts where you're doing as many reps as possible in one minute, you should feel your breathing get so heavy
that you can speak only a word or two at a time, McMillan says. If your form starts to break down, dial back the
weight to avoid injury. He recommends using the one-two rep test: In your final set, you should feel as if you're
barely able to do the final one to two reps with good form. If you have more juice left in your muscles, try another,
shorter round with slightly heavier weights.
