Ab workouts and when to avoid them...
Contrary to popular belief, hundreds of sit-ups won't make much
difference to the appearance of your waist and stomach if your abs
are hidden under a layer of fat.
Fat is stored energy. To get rid of the fat, you have to burn more
energy (calories) than you eat on a regular basis.
What's more, a lot of bending exercise first thing in the morning
puts a lot of stress on the discs in your back.
Why?
You’re taller when you wake up in the morning than when you
go to bed at night.
That's because the discs in your back are hydrophilic (pronounced
high-dro-fill-ick). In other words, they suck up water while you
sleep.
First thing in the morning, these discs are like a balloon full
of water. And, if you do a lot of bending (like ab workouts that
involve sit-ups or touching your toes), there's a lot of stress
on those discs. In fact, the stresses are three times higher than
when you perform the same exercise two or three hours later.
That's one reason why putting on your socks in the morning feels
a lot harder than taking them off at night.
"Researchers have documented the increased annulus stresses
after a bout of bed rest," says Professor Stuart McGill, an
expert in spine function and injury prevention and rehabilitation
at the University of Waterloo in Canada.
"Yet many athletes and laypeople alike get up in the morning
and perform spine stretches, sit-ups, and so on. This is the most
dangerous time of day to undertake such activities."
Some evidence for this comes from research published in the journal
Spine [1]. The study shows that controlling lumbar flexion
in the morning is an effective way to reduce back pain.
A group of 85 subjects with persistent or recurring low back pain
was assigned to one of two groups.
One group was told to restrict the amount of bending they did in
the early morning. The control group received a "fake"
treatment consisting of six exercises shown to be ineffective in
reducing low back pain.
After six months, back pain was reduced in the group told to restrict
bending activities in the early morning.
A follow-up study shows that participants who continued to restrict
bending activities in the early morning enjoyed a further reduction
in back pain [2].
The bottom line is that doing your ab workouts — or any type
of exercise that involves a lot of bending — is one of the
worst things you can do for your back first thing in the morning.
After you get up, just walking around helps to "squeeze"
the fluid out and compress your spine. If you want to do your ab
workouts early in the day, wait for an hour or two after getting
out of bed. Your back will thank you for it.
