While most people’s gym routines differ – I, for one, have always been an elliptical girl and hate the stationary bike – it’s safe to assume that almost everyone incorporates a “cool down” into their cardio program. After running for 30 minutes at 7 miles per hour, you’ll knock your speed down to 3 and spend five minutes jogging or walking before you hop off the machine. Many pieces of gym equipment even include a 5-minute cool down automatically, tacking it on to the end of your desired workout. All of this is supposed to prevent soreness or muscle damage and relieve strain on the heart.

According to University of Texas physiologist Hirofumi Tanaka, however, there’s no proof that a cool down has any positive benefits on the body. “Everyone thinks it’s an established fact, so they don’t study it,” he said in a recent New York Times article. The article notes the ambiguity of the concept as a whole, noting that it’s not even clear what a cool down is supposed to be or how long it should last.

Apparently, the cool down became standard gym practice after it was reported that muscles become sore after exercising due to the accumulation of lactic acid. This theory has been reported false, leading people to believe that reducing the intensity at the end of a workout (which was supposed to let the lactic acid dissipate slowly) is unnecessary. The article does note, however, that blood can build up in your legs and feet if you stop running (or biking or ellipti-cizing) shortly, making dizziness or even fainting a possibility. Read More »

Now that half my friends are on a diet, thanks to effing New Years, I have to share something with y’all. You know that bathroom scale that you get on every morning? It’s lying to you. You heard me. It’s lying. So, everyone can just stop freaking out about what it told you this morning, because it probably isn’t true.

There are a multitude of factors, from water consumption to plain old hormones, that can artificially – and temporarily – affect that ever important number on the scale, anywhere from 1-5 pounds in a day.

#1. Water water water.

Water can affect your weight in a couple of ways: drinking too much, and not enough. As a substance, water is pretty heavy, so if you drink a couple big glasses, you’ll see an immediate impact on your weight. On the other hand, dehydration can also lead to a higher number, because it causes the body to retain what water it does have (it thinks there’s a draught or something?). Our bodies are made of 60% water, so any changes in that arena are going to have a noticeable impact overall.

#2 Food

This one seems so obvious, but people sometimes forget that food weighs as much in your stomach as it does on your plate, at least initially. Take that into account when you step on the scale, or better yet, wait ’til you’ve digested before you get anywhere near it. Read More »
