This video explains how the amount of shoulder rotation you get during a windshield wiper forehand can differ from a classic forehand. After you hit the tennis ball, you typically have to rotate a little bit more than you otherwise would on the windshield wiper. There are a number of reasons for this, but in this video we keep our focus relatively narrow.
Every time you hit a tennis forehand you choose how you position your feet -- what stance you will use. You can hit a forehand with an open, neutral, or closed stance, but you should stay away from the closed stance if possible. This last stance makes it difficult to rotate your upper body through contact, making it difficult for you to use correct forehand mechanics.

There are plenty of reasons to upgrade to iOS 14, home screen widgets chief among them. With that in mind, it's ironic that Apple placed so much emphasis on "widgets" this year when the new update removes a fan-favorite widget of the past — the "Favorites" Phone widget, which was accessible via the Today View or quick actions on the home screen. Here's how to get it back.
The original iPhone SE was, for some, the perfect iPhone. It brought back the popular one-handed form factor of the iPhone 5 but packed in the internals of the then-new iPhone 6S. Now, the second-generation iPhone SE is here for 2020, but can it live up to what made the first-generation iPhone SE so popular?
One of my favorite perks of this job is the opportunity to try out all the big flagship phones each year. Whether it's rating their suitability for a particular use-case or just entering their specs into our comparison tool, we have to get our hands on all major phones released in the US. We pride ourselves on being fair in our reviews and roundups, but that doesn't mean we don't have preferences.
In a bold move, Samsung has decided to forgo the Galaxy S11 moniker and jump straight to the S20. Perhaps it's marketing for the new 20:9 aspect ratio and 120 Hz display, or maybe it's just the fact that it's releasing in 2020.
It's finally out. After months of testing, iOS 13 is available to install on your iPhone, which means over 200+ new features you can use right now. The update, released on Sept. 19, can be installed over the air or from a restore image using iTunes in macOS Mojave and older or Finder in macOS Catalina. Ditto for the 13.1 update issued on Sept. 24.
Beta testing certainly has its perks. While you do need to deal with bugs, you're introduced to new features before the general community. And if we're talking iPhones, there are over 200 new features in iOS 13 beta. If you're already on board with iOS 13 public beta 6 for iPhone, you can get an upgrade on that firmware as Apple just released public beta 7 today.
You might think you need to buy a thousand dollar phone to get a great experience while streaming movies and TV shows from services like Netflix, Hulu, and YouTube, but that's just not true anymore.
