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.

Lab tested. Lab approved.

My two Labradors make quick work of these. They love them. But Not very durable. Stuffing everywhere.

Our dog loves them
Style: Latex Surpise Color, Size: 6"
Not for every type of dog, but our dog LOVES these things. Try one and see how it goes. They are cheap, so no great loss if your dog doesn't like it, But if it does, you'll have a great time with them. Best $3 I could spend

Tie a Knot in it if it rips
Style: Plush Surprise Color, Size: 6", Style: Plush Surprise Color, Size: 6"
My puppy split the middle belly seam in about 5 minutes of spirited play with the white foam and squeak assembly scattered about, but he loves these loofa toys - goes nuts for them. Went through a couple of the little $3 ones so I tried this big one which he ripped apart. But I tied a knot in the middle of it over the ripped part and guess what, it's better than before. He loves the whipping the big knot around. The part where it ripped was where they filled it I think but the rest of the stitching is really quite solid. Takes a beating, to a point. The little ones lasted a reasonable time before they were totally played.

Do research
Size: Small
My pups love to shred things. This was a good toy for them to satisfy their need to shred things. My dogs are on the smaller side and I went with a small. I do encourage people to do their research and not leave this toy unsupervised. If your dog eats toys they shred this might not be a good toy for you. Coconut fiber can become impacted if too much is consumed. Unlike other reviewers I didn’t notice to much of a mess outside any other toy a dog might shred.

Not Suitable for Power Chewers
Size: Large
Coconut fiber toys aren’t ideal for heavy chewers. They shred easily, can be swallowed, and may cause choking or intestinal blockages. The coffee wood is a safe durable product and loved but my dogs. I wish I would have done more research before buying the coconut fibers chew.
