Warm-ups often feel useless — especially when compared with a rousing cardio session or circuit workout. But in fact, a focused, intelligent warm-up offers multiple benefits, including boosting core temperature, circulation, and metabolism; improving spatial awareness and alignment; firing up dormant muscles — and focusing your mind.
If you make a living at a desk, warming up is especially critical. Sitting for prolonged periods of time can cause key ligaments in your spine to overstretch, leaving you stuck in a closed-off, or flexed position.
“Lots of people come into the gym looking like a giant ball of flexion,” says Tony Gentilcore, CSCS, owner of CORE Fitness in Brookline, Mass.
Working out in this condition is like driving with the brakes on, he explains. A good warm-up will open up the front of the body and rouse your back muscles; this helps restore proper alignment so you can lift, run, and play with greater power, efficiency, and fluidity.
Learn to do a warm-up well and, after just a few sessions, you’ll feel a major difference.
“Once people get the hang of warming up correctly,” says Gentilcore, “most of them feel so good they never go back to skipping their warm-ups again.”

Sleep Deficiency Hinders Weight Loss, So Try Better Sleep Habits
Do you wake up feeling tired? Well, you’re not alone. One in every three Americans does not get the recommended sleep needed for optimal health, according to the Centers for Disease Control and Prevention (CDC).
Sleep deficiency is known to cause weight gain, but also contributes to a whole list of more serious health issues, such as heart disease, high blood pressure, depression, and diabetes, just to name a few.
Why Sleeping Is So Important for Weight Loss
Believe it or not, each and every day the most important thing that you do all day is sleep. Yes, you heard right! Sleep quality and duration are so important that they directly affect everything else you do in life.
“We are nothing but slaves to chemical processes,” says W. Christopher Winter, MD, in an article for Livestrong.
Nearly one third of our lives are spent asleep. During sleep, it is peak time for our bodies to repair muscle and release hormones that control natural processes, including appetite. All this is being done without any conscious energy being consumed.
Consequently, a deficiency in the sleep column affects everything; more specifically, it cuts weight loss and exercise performance by nearly 20%. This spirals into a decrease in hormone production, (which occurs when we sleep), and ultimately affects our daily eating pattern. Popular studies show that weight gain occurs because more calories are consumed on the following day, because of lack of hormone release. Therefore, a continued deficit during the night will only lead to months and years of unnecessary weight gain. On the flip side, if you aren’t already experiencing weight gain, you may just be unable to lose weight at all. So you don’t have weight gain, but no weight loss occurs, either.
Practice Better Sleep Habits
The best advice is to practice better sleep habits, getting optimal rest and avoiding insomnia.
Start with controlling your sleep environment by setting it at the appropriate temperature. Experts suggest trying between 60 and 67 degrees Fahrenheit. Try eliminating all computers and television sets from your room as well, since any source of light tends to disrupt sleep patterns. Aim for consistency rather than trying to catch up on hours you might have missed the preceding day. Don’t be afraid to take short naps when feeling fatigued. These should be anywhere from 20 to 30 minutes long to help improve alertness, performance, and mood. Lastly, never consume caffeine in the afternoon because it has the ability to stay in your system and interrupt the natural onset of sleep several hours later (See our blog on giving up caffeine).
The final verdict is in. A poor amount of sleep greatly hinders weight loss and sets you up for other health problems. So do yourself a favor: turn out the light, tuck yourself in, and get some much-needed Zzzs.

Caffeine Free: Breaking the Habit
Like most people, I’m busy: full-time job, kids, a house… and in my “spare time,” I’m a high school tennis coach and play a lot of tennis. A few years back I started having issues with exhaustion (go figure). Right around 4pm I would just be overcome with complete, hit-the-couch, exhaustion. The only way to make it through the rest of my busy day seemed to be one more caffeinated drink.
I’m not a coffee drinker, so my drink of choice to get going in the morning was an AdvoCare energy drink called Spark®. I loved my Spark®, probably as much as most people love their coffee. I personally had no issue with using stimulants to keep me going through my day, but that changed one day recently on my drive home from work.
The Impact of Stimulants on the Brain
While listening to Fresh Air on NPR, I heard a discussion on sleep with sleep scientist Matthew Walker. Part of the talk discussed the effects of caffeine on the brain and how it alters the natural functions of the brain, including the buildup of adenosine. Adenosine is a chemical in the brain that builds up throughout the day, edging you to sleep. Caffeine comes into the brain and masks the effects of adenosine on the brain so that you are fully awake. One problem is that adenosine continues to build up, so when the caffeine wears off, you have additional levels of adenosine in your brain. This creates the effect we know as caffeine crash.
This made me think about what I had been putting in my body and the fact that I was using caffeine to mask the real issue I was having: not enough sleep. This one show made me rethink how I was treating my brain and how I had allowed caffeine to creep solidly into my everyday habits. It also reminded me that I was disregarding the need for one of the most critical things needed by the body and brain, sleep.
Giving Up Stimulants and Getting More Rest
Three months ago, I quit caffeine drinks cold turkey: no Spark®, colas, or energy drinks. In addition, I put the theory to the test and began carving out eight hours for sleeping each night. At first it took a bit more structuring, but now I don’t allow myself not to get a full night’s rest.
The results have been pretty amazing to me. In the first few weeks after quitting caffeine, I can honestly say that I was not tired. My energy levels were good all day and I was tired at the right time in the evenings, leading up to a decent bedtime and better sleep. I have also lost the cravings I had for those caffeinated drinks, which is an added bonus since I didn't have to worry about ordering more Spark® each month.
Many will tell you there are pros and cons to quitting caffeine but for me its one of the best things I have done for my health recently. Cutting caffeine has allowed my brain to function the way it was meant to, without a stimulate to interfere. For me, that is a step in the right direction.

4 Common Habits Sabotaging Your Sleep
In addition to proper nutrition, hydration and recovery days, sleep can be one of the top factors that can make or break your fitness performance.
In a recent study looking at sleep quality and athletes, researchers noted that people who are in training tend to experience more sleep issues than non-athletes, due to training load and stress. The study also suggests athletes require more sleep than those who don’t work out because they have higher recovery needs.
But knowing that you should sleep and getting that sleep can be two very different things. When dreamtime proves elusive, there tends to be a slew of common sense strategies people use — yet it’s possible that, for some, those allegedly proven tactics are actually making the problem worse. Here are some habits you might be putting in place that are keeping you from getting enough shuteye:
1. TAKING MELATONIN AT THE WRONG TIME
Around sunset, your brain produces melatonin, a hormone designed to start a cascade of sleep-inducing reactions. But if you’re frazzled or anxious, the hormone might not be as abundant as you’d like. Because of that, many people turn to taking a melatonin supplement.
But they often pop it like a sleeping pill right before bed, thinking it’ll take effect immediately, according to W. Christopher Winter, MD, president of Charlottesville Neurology and Sleep Medicine. Melatonin in the body tends to take around 3–4 hours, so if you’re taking it at 9 p.m., you might not sense any effects until about 1 a.m. — by then, you could be so frustrated by insomnia that you’re up watching TV instead, which will lower that melatonin back down.
2. GOING TO BED ONLY WHEN YOU’RE SLEEPY
Schedules become variable especially as seasons change — you stay out later on those bright summer nights, for example — and that can lead to hitting the sack when you’re tired. But too much variability can leave your body unsure about when to actually sleep, according to Mia Finkelston, MD, family practice physician.
“We can handle some changes to our usual routine, but not as much as you might think,” she says. “When you go to bed only when you’re tired, you’re introducing too much unpredictability into your sleep schedule. And that can catch up with you.”
3. COUNTING SHEEP (OR ANYTHING)
Some yoga and meditation breathing techniques rely on counting each inhale and exhale, so it makes sense that you might try to import that to your sleep routine. But Winter says some people find counting to be an anxiety-provoking exercise, instead of the de-stressor it’s meant to be.
“Maybe you get anxious if you hit double digits and you’re not asleep yet,” he says. “Or, you might have fallen asleep around 30 the night before but now you’re nearly at 50 and still counting. Then you might wonder if you’re doing something wrong.”
When that happens, it can sabotage your sleep efforts. Instead of counting, he recommends visualizing a well-known process that’s calming to you. For example, one of his patients “bakes” every night — she envisions getting out the measuring cups, chopping up ingredients, arranging the bowls for flour and sugar — and has found the process so effective, she jokes that nothing ever makes it into her imagined oven.
4. CHECKING THE CLOCK
Although it might seem like it would be a relief to know you have five hours left until you have to get up, looking at the clock is a bad habit, says Finkelston. It can be so counterproductive that she’s even advised some patients to put their alarm clocks in another room or the closet.
“To recognize how much time you have left to sleep, you have to wake up to a certain degree,” she says. “That might be just enough to kick you out of your cycle and cause some insomnia.”

BETTER HABITS, BETTER SLEEP
In general, it helps to play around with different strategies to see what works for you, says Winter. If melatonin is your jam and it’s working, that’s great. But if you’ve tried it for week or so and you’re still staring at the ceiling for an hour, then try switching it up instead.
“The last thing you want to do is try to force something to work, because then you’ll be agitated when it doesn’t,” he says. That can increase levels of cortisol — the hormone responsible for your stress response — and you’ll be back where you started.
Instead, try implementing good sleep practices, where consistency is key. Limit screen time before bed, set a regular bedtime and get up at the same time every day (yes, even on the weekends, sorry). Winter suggests starting a “wind-down routine” about a half-hour before bed, which can help send a signal to your brain that it’s time to relax.
