When we are young, exercise can enable us to run a race
after an all-nighter or snowboard on a diet of Doritos. But as we age, fitness
has a much more far-reaching impact, boosting our energy levels, preventing
injuries, and keeping us mentally sharp.

Aging causes muscles to lose mass, bone density to thin, and
joints to stiffen — affecting our balance, coordination, and strength. At the
same time, hormonal shifts and persistent low-level inflammation can set the
stage for chronic diseases such as cancer, cardiovascular disease, and
diabetes.
And the changes start earlier than you might think. Muscles
begin to shrink in our 30s and continue their downward spiral in midlife, with
up to 25 percent of their peak mass gone by the time we are 60.
But there is hope: Exercise can stall muscle loss, cognitive
decline, and fatigue.
“It’s never too late to start exercising, and it’s never too
early,” said Chhanda Dutta, a gerontologist at the National Institute on Aging.

You cannot just start dead-lifting 70kg at the gym, though.
Start slow, experiment, and gradually amp up the intensity.
Experts suggest trying exercises that target one or more of
four categories of fitness, all of which deteriorate with age: flexibility,
balance, endurance, and strength. Preserving function across these domains can
stave off injury and disability, keeping you active and independent longer.
There is no magic-bullet, full-body exercise to forestall
aging, said Dr Brian Feeley, the chief of sports medicine at the University of
California, San Francisco. Here are five movements, targeting different areas
of the body, to try.
Strengthen the lower body: Squats and stairsDuring exercise, “injuries happen when you’re fatigued, and
your muscles can’t react as quickly,” Feeley said. Squats help prevent this
fatigue by strengthening the large muscles in your lower body while moving
multiple joints at once, which improves overall endurance as well as balance
and coordination.

60-year-old actor and model, hangs from a pull-up bar in New York.
Feeley suggests doing three sets of 10 to 15 squats four
times a week. To further challenge your balance, do them with one foot or both
feet on a pillow. Or to focus on strength, squat while holding free weights —
close to your chest to start or extended in front of you to work your core
more.
If you loathe squats but still want to strengthen the same
muscle groups, try climbing stairs, which is adaptable to different fitness
levels, said Dr Maria Fiatarone Singh, a geriatrician at the University of
Sydney. Start by walking up and down the stairs, and graduate to sprinting or
wearing ankle weights.
Get your heart rate up: Take a Nordic walkAs a cross-country skiing enthusiast, Dr Michael Schaefer, a
rehabilitation physician at University Hospitals in Cleveland, loves Nordic
walking — an exercise using ergonomic poles that uses the same movements. No
snow required.
“Nordic walking is unparalleled as an aerobic exercise
because you’re not just using the major muscle groups of your legs and hips,
but your core, shoulders and arms too,” Schaefer said.
“Nordic walking is unparalleled as an aerobic exercise because you’re not just using the major muscle groups of your legs and hips, but your core, shoulders and arms too,”
The regimen lowers blood pressure and improves the body’s
use of oxygen. And when you traverse hills or uneven ground, you are
strengthening your ankles and challenging your vestibular system — a sensory
system housed in the inner ear that enhances balance and coordination.
“Start with 15 to 20 minutes three times a week and work up
to one hour,” Schaefer advised.
The basic movement — walking, using poles to propel your
movement — can take some getting used to, but online videos or your local
Nordic walking group can get you started. The key is to swing your arms as if
they are clock pendulums, keeping the elbows relatively straight and planting
your pole behind you and pushing off as your opposing leg strides forward.
Train your upper body: Try hanging aroundIf Katy Bowman, a kinesiologist, had her way, everyone’s New
Year’s resolution would include a trip across the monkey bars.
“It’s such a primal movement and uses all these parts of our
upper body” that otherwise do not get used very often, said Bowman, the author
of “Rethink Your Position”.
Nordic walking uses
the torso to help propel the body forward.
Hanging from a horizontal bar enhances grip strength and
shoulder mobility, strengthens the core, and stretches the upper body — from
the chest to the spine to the forearms.
As with any exercise, it is best to progress slowly — start
by hanging on a bar with your feet supported on a box or chair so that muscles
unused to carrying a load can become accustomed to bearing some tension. From
there, proceed to an active hang, in which your shoulder blades are retracted
and pulled down (as if you are about to start a pull-up), your core and arms
are engaged, and your hands are about shoulder-width apart.
Hanging from a horizontal bar enhances grip strength and shoulder mobility, strengthens the core, and stretches the upper body — from the chest to the spine to the forearms.
Add a slight swing front to back or right to left to work the
core and spine even more. Or mix up your grip — hands facing away from or
toward you, or one of each — to emphasize different muscles. An underhand grip,
for example, loads the biceps more than an overhand grip, which works the lats.
And you do not need fancy equipment to hang. Bowman
suggested creating a hanging station in your home with a “$20 doorway chin-up
bar that doesn’t take up much of a footprint”. Since she has installed one, she
said, she has noticed a “radical” increase in her upper body and grip strength
— which is linked to a decrease in all-cause and cardiovascular mortality. A
little goes a long way too: Begin with 20-second hangs, twice a day, working up
to a full minute.
“Frequent, shorter hangs distributed throughout the day are
your best bet for making progress,” Bowman said.
Once you feel comfortable with one-minute hangs she
recommended eight to 10 of them, with an hour’s rest in between. These breaks
also give the skin on your hands some time to adapt.
Strengthen your core and hips: Use a sliderIf you work at an office or a desk, all of that sitting can
do a number on your hip flexors, the muscles that help you bend your knees
toward your waist and stabilize your spine. And hunching over a desk shortens
the muscles in the chest while lengthening those in the back, contributing to
text neck, which is muscle strain and weakness of the lower neck, shoulders,
and upper back.
To counteract this, Nicole Sciacca, a mobility specialist in
Los Angeles, pairs mountain climbers with sliders — small disks on which you
rest your hands or feet that slide freely on the floor (or, you can use paper
plates). Training on an unstable surface increases the intensity of an
exercise, forcing you to engage your core — especially the diaphragm,
transverse abdominis and pelvic floor — to maintain position.
“It’s great because it asks everything along the front side
of the body that’s been sleeping at a desk or in a car to get stronger,”
Sciacca said.
Muscles begin to
shrink in our 30s and continue their downward spiral in midlife, with up to 25
percent of their peak mass gone by the time we are 60.
If you are new to working your upper body and core, Sciacca
suggests holding a simple plank for 30 seconds. Once that is comfortable,
position your feet on the sliders, assume the same position, and work to keep
yourself stable.
To progress, move one foot in under your body until your
knee reaches your chest. Slide that foot back out while your other foot comes
in. Continue alternating your feet for up to three rounds of eight reps,
keeping the core strong and the back straight. Or try a timed effort of 60
seconds when you are ready for more. Variations include bringing your knees in
and then out at the same time or sweeping your legs out in a jumping-jack
motion.
Improve your flexibility: Foam rollTala Khalaf, a physical therapist at Stanford University in
Palo Alto, California, thinks of fascia — a system of connective tissue that
wraps around our muscles and organs — as the Cinderella of orthopedic medicine.
For years, this tissue, which is studded with sensory nerves and can look like
a sheath around the outside of muscles or found within them, toiled away in
obscurity, ignored and minimized.
But research in the past decade has lifted up fascial tissue
as a crucial component of the musculoskeletal system. As we age, fascia becomes
less pliable and elastic, which contributes to back pain, stiffness, and a
limited range of motion.
Khalaf, who is also a faculty member at Stanford’s
Orthopedic Physical Therapy Clinical Residency Program, said one solution was
foam rolling, which massages out the fascial kinks and improves flexibility.
Best of all, the basic moves are simple and time-efficient. Typical areas to
roll include the calves, thigh and back. Experiment to see which exercises
provide the most relief.
