You work out, you eat right, you take your multivitamin. You wash your hands—maybe you even wear a mask in the drugstore.

Strength and conditioning science for hockey has never been better than it is right now.
Leading the way: NCAA schools increasing their budgets for athletic training. Â True, much of this budgeting is toward athletic training for basketball and football (the big moneymakers) but the carryover has been great for hockey.
Unfortunately, there's also a lot of BAD information out there for hockey players. Â Stability balls, balance boards, and wobbly surfaces are prevalent - not because they work, but because the Strength and Conditioning Coaches for the pl...

Plyometrics play an important role in the development of any athlete. Â They're effective at turning strength into speed, which is critical in every sport. Â In a simple linear plan for training an athlete, plyometrics would fall between power generation and speed development. Â However, many coaches use them as a substitute for strength training exercises, or as a sport-specific developer of anaerobic capacity, which misses the point.
Â
How They Work: Â Plyometrics (as defined by a rapid stretch-shortening cycle in muscle fibre) improve speed by increasing Rate of Force...

Investing In Yourself
Â
Last night, I opened an envelope from my financial advisor. Â If you've received one of these, you know the next part already. Â My loudness almost woke up my kids. Â Unlike our anatomy, our savings and investments should improve with time. Â I don't know much about that, but I spend a LOT of time with human bodies, and there's one thing that's true of all of us: we're on a downward slope. Â Rage, rage as much as you want, but you're not going to be as strong when you're 70 as you are now (unless...

Insulin is your internal UPS. When you eat, and your blood glucose level rises above 90 mg/dl, the pancreas kicks out insulin to start moving blood sugar and other nutrients around. Without insulin, you couldn't digest food; you could literally eat all you want, and none of it would reach the muscle cell, and you'd starve to death. Insulin, obviously, is a critical hormone.
Unfortunately, insulin is an equal-opportunity dump truck. It doesn't care what gets dumped where; it just looks for a big 'VACANCY' sign and fills accordingly.
Â
When blood sugar's rising t...

Why You Get Hangry (And How To Stop)
Ever found yourself snapping at someone only to realize that, actually, you’re just really hungry? You’re not alone; it’s a universal feeling we fondly call being “hangry” – a blend of hungry and angry. But why does this happen, and more importantly, how can you stop it?

100% Is Easier Than 98%
Maintaining a habit is easy and gets easier.
Stopping and starting is hard and gets harder.
If you do these things every day, they just become part of you. But if you skip a day, then every future day becomes optional. That means it becomes hard, because you go from "no decision" (just doing what you do) to making a decision every time.
We all have decision fatigue: we make decisions all day long and it gets harder and harder to choose the decision that will help us...
