#1 NEW YORK TIMES BESTSELLER - The game-changing author of Tribe of Mentors teaches you how to reach your peak physical potential with minimum effort.

"A practical crash course in how to reinvent yourself."--Kevin Kelly, Wired

Is it possible to reach your genetic potential in 6 months? Sleep 2 hours per day and perform better than on 8 hours? Lose more fat than a marathoner by bingeing? Indeed, and much more.

The 4-Hour Body is the result of an obsessive quest, spanning more than a decade, to hack the human body using data science. It contains the collective wisdom of hundreds of elite athletes, dozens of MDs, and thousands of hours of jaw-dropping personal experimentation. From Olympic training centers to black-market laboratories, from Silicon Valley to South Africa, Tim Ferriss fixated on one life-changing question:

For all things physical, what are the tiniest changes that produce the biggest results?

Thousands of tests later, this book contains the answers for both men and women. It's the wisdom Tim used to gain 34 pounds of muscle in 28 days, without steroids, and in four hours of total gym time. From the gym to the bedroom, it's all here, and it all works.

You will learn (in less than 30 minutes each):

- How to lose those last 5-10 pounds (or 100+ pounds) with odd combinations of food and safe chemical cocktails
- How to prevent fat gain while bingeing over the weekend or the holidays
- How to sleep 2 hours per day and feel fully rested
- How to produce 15-minute female orgasms
- How to triple testosterone and double sperm count
- How to go from running 5 kilometers to 50 kilometers in 12 weeks
- How to reverse "permanent" injuries
- How to pay for a beach vacation with one hospital visit

And that's just the tip of the iceberg. There are more than 50 topics covered, all with real-world experiments, many including more than 200 test subjects. You don't need better genetics or more exercise. You need immediate results that compel you to continue.

That's exactly what The 4-Hour Body delivers.

Great toy that stands up to tough dogs
Size: 5 Pack
When these toys first arrived and I opened the box I was disappointed. They seemed a bit flimsy and were not what I was expecting Boy was I wrong! My dog lived his new toy and it’s has not left his side. Best of all, it’s a tough little toy that can take a beating and keep going. My dog usually tears through his toys in a matter of hours, and I tried numerous toys over the years. I’ve tried Kevlar toys, toy that claim to be very sturdy, he always destroyed them in a matter of hours. This toy looks flimsy, but it’s soft and strong

Solid dog toys HOWEVER...
Size: 5 Pack
Got these toys for our collie-retriever. He loves them and plays with them a lot and will even get them out in the middle of the night to play with them. Since there's no stuffing you can't throw them very far but they are good for tug-of-war and really soft. The one downside, while they techically are durable and hold up to rigorous chewing, they are not impervious as our little man finally disembowled Mr. Lion after a few months of playing with him. (Serated the lining with his teeth.) Still highly recommend.

Nice but not durable for Dobermans
Size: 5 Pack, Size: 5 Pack
They are cute and I like that there is no stuffing. But they are definitely not for large Dobermans. They ripped the head off within 10 minutes of playing. Which I expected be a no toy lasts longer than 30 minutes.

worth the price !
Size: 5 Pack, Size: 5 Pack
Best toys for our livestock puppies since they have been getting into our outdoor things which isn’t their faults but i figure I would get these small squeaky animals toys and they are obsessed and love playing tug a war with them! They’re super soft, the quality is amazing cause these puppies are tough chew monsters, love the squeaky sound it makes and the patting are suitable as well! Definitely recommend this especially for the price and how fast shipping was !
