Award-winning journalist, physicist, and bestselling author of Endure Alex Hutchinson reveals the little-known and often surprising truths that science has uncovered about exercise, ranging from cardio and weights to competition to weight loss.
There's plenty of conventional wisdom on health and fitness--but how much of it is scientifically sound? The truth is: less than you'd think.
In Which Comes First, Cardio or Weights?, physicist and award-winning journalist Alex Hutchinson tackles dozens of commonly held beliefs and looks at just what research science has--and has not--proven to be true:
- Should I exercise when I'm sick?
- Do I get the same workout from the elliptical machine that I get from running?
- What role does my brain play in fatigue?
- Will running ruin my knees?
- To lose weight, is it better to eat less or exercise more?
- How should I adapt my workout routine as I get older?
- Does it matter what I'm thinking about when I train?
- Will drinking coffee help or hinder my performance?
- Should I have sex the night before a competition?
This myth-busting book covers the full spectrum of exercise science and offers the latest in research from around the globe, as well as helpful diagrams and plenty of practical tips on using proven science to improve fitness, reach weight loss goals, and achieve better competition results.

Immediate results
Item Package Quantity: 1
Very easy to apply. Impressive immediate results. However not yet sure if the shine will last. It’s only been 48 hours but so far it’s great and definitely worth the money. I give it 4 stars for now. If the shine lasts it deserves 5 stars.

It does work but
Item Package Quantity: 1, Item Package Quantity: 1
I recently bought a small general purpose utility vehicle. Because it was a tow along vehicle behind a motorhome since it was new it is in remarkable condition. That is except for the headlights. They actually aren’t yellowed with age but cloudy from exhaust fumes from the motorhome. Such a haze is hardened and doesn’t even scratch with a fingernail so I had very low expectations for this vehicle.
WHAT YOU GET
I looked at the listings for all of the famous brands, I chose this one primarily on price, after all I only bought this vehicle for quick errands around the neighborhood. I accept responsibility for not reading every word of their ad, but because I have used many well-known brands of headlight restorer in the past I know that most of them have enough so you can do a couple of vehicles at least. So I was completely not expecting getting three small packets of wipes. That’s it. It can be used only one time and now compared to the kits with bottles that can do several sets of headlights that cost twice as much I see this one is a not such a good value as I thought. And I never buy anything that comes as a wipe, usually by the time I get them they are already dried up, which makes them useless, that’s why they always have an expiration date. I changed my plans and went to work on the Jeep immediately to see if I could make those headlight lens covers usable (they look like sealed beams but the lenses are meant to protect the headlamps).
YES NO MAYBE
I can’t blame the ad, after reading it again they do state that these are only single use wipes, which means if you start a project you have to finish immediately. Hint: never use wipes on a hot day, they will start drying up as soon as you open the envelope and if the day is hot enough you might not even get through the job before they are totally dry. If I knew how these differed from the well-known brand names I would have made the choice to buy something in a bottle so I can use a real cleaning cloth and re-wet it if necessary. Did these clean my headlamp lenses? As a shopper all you want to know is yes or know, did it work and am I satisfied. The conclusion is they exceeded my expectations. The application process could not be easier, and note that well when some random person approaches you at a gas station and offers to clean your headlights, these are so easy my great-grandmother could apply them. You wipe the lenses with envelope #1, not rub, not scrub, just a simple wipe to make sure you get all of it. I was able to also do my clear lens fog lights which were equally crusted over. Make sure you dry them with a paper towel then let them air dry for a little while. I’m not sure what you would do if you live in an extremely high humidity area, and the manufacturer doesn’t address that. It was a dry day for me so I gave it fifteen minutes. Then you wipe the entire lens with packet #2 – again I was able to do two headlights and two fog lights with one swab. My headlight and fog lenses instantly turned crystal clear like they looked the day the car was made. I should take away a point because I didn’t expect this kit to be only three small envelopes with wet wipes in them but they don’t try to pretend otherwise and results are 100% of why I rated them a full five stars.

It really works!
Item Package Quantity: 1
This worked exactly as it says, and turned what looked like an old vehicle to a shiny new one. The only ugly thing about the car was the cloudy headlights. Everything else looked great. It really ages a car when it has cloudy headlights. There was no rubbing or buffing, just easy wiping and drying in one more wipe. The video was very helpful on the website.
