The sports world loves nothing more than the great upset. When one comes along, fascination follows. How could this happen? What change made it possible?

One of the biggest topics of conversation in golf right now is speed -- specifically, how to create velocity in the swing. In this episode of Fitness Friday, we talk about controlling and connecting your upper and lower body to create a safe, balanced speed in your swing. Grab your medicine ball and let's get to work! 

You count your reps at the gym. You count your minutes on the treadmill. You count your calories at the dinner table. There are a lot of numbers to pay attention to when trying to get fit. Well, the number of numbers you should be paying attention to just got bigger. Thanks to WHOOP, you can now quantify and keep track of how well you recover from the physical and mental stresses of your day-to-day life. And it can be an invaluable tool for golfers looking to improve their fitness levels -- whether you're a scratch golfer or you're just a beginner.

If you're a golfer living in the northern two-thirds of the country, this is a special time of the year. It's no longer dark at 4:30 in the afternoon, weather forecasts stop mentioning snow, and temperatures start to creep into the 50s and 60s. Winter is over and, well, it's time to hit some balls. But just because the calendar is telling you it's almost golf season, it doesn't necessarily mean your body is ready to hit the course. Fear not! Hit IT Great has you covered.

To be the best, you need to work with the best. In the culinary world, it means being in the kitchen with a Michelin-starred chef. In the film world, it means being on the set with an Academy Award-winning director. And when it comes to your golf game and your golf swing, it means working out with the top strength, conditioning, and biomechanics coaches in the sport. And that's what Hit IT Great is all about.

Bryson DeChambeau swings the golf club really, really hard. Should you be doing the same?

You're in the middle of your third of eight Zoom meetings for the day. Yes, you realize that having a meeting about planning the next meeting to review the minutes of an earlier meeting is vitally important, but -- deep down -- all you're really thinking about is the next time you'll be able to tee it up.

If you've been reading our blogs and eBooks for any length of time, you know that when it comes to training our players we take a Big Picture look at how the body factors into the golf swing. And it doesn't matter if that player just won $15 million and the FedEx Cup or if he just won $80 bucks and his weekly foursome. If you're looking to play your best, you have to train your entire body to be successful. But while a lot of players may do some quality upper-body training and lower-body training, many may be sabotaging their game by not focusing enough -- or correctly -- on the thing that ties the upper-body and lower-body together: the core.

In the fitness world, there’s a lot of emphasis on building strength through resistance training, whether you’re pumping iron or using your own bodyweight. There’s a good reason for that: increased strength comes from lifting increasingly heavier things over and over again. But strengthening alone won’t necessarily translate into bigger drives. To get the most out of your body, you also need to be focusing on flexibility.

It's kind of ironic that I'm writing a blog about senior golfers on the week of my birthday. These days, birthdays don't seem to have quite the same excitement as they did when I was eight or nine years old. But getting older doesn't mean your golf game can't get a lot more exciting. Golf fitness isn't just for players on The Tour. These 3 simple golf exercises for seniors will not only help improve your game, but they'll also help prevent injury and have you feeling better both on and off the course.
