The Activity Rings on your Apple Watch don’t provide a complete picture of your fitness. There is one important ring missing: Strength. The Rock didn’t get ripped just by standing up once an hour. And both the Exercise and Move rings essentially measure the same thing: cardio.

As any fitness expert will tell you, an effective workout program should combine cardio with strength training. Here’s why strength is currently Apple Watch’s weakness, and how you can use third-party apps to make sure it isn’t yours as well.

If you got started on your 2017 New Year’s resolution last week with our CultFit Home Workout, we’re here to help you keep up the good work with Week 2. (If you missed it, it’s still not to late to start with Week 1).

All you need is your iPhone, plus your Apple Watch if you have one, and some everyday objects you’ll find around your home or office. No gym membership required. It’s a great way to get started with your fitness journey, and it only takes 10 minutes a day.

Some Apple Watch users are apparently confused over what types of exercise the wearable’s Workout app can track. Many people are using it to log weightlifting or stretching sessions, even though Apple only claims the app is suitable for “dedicated cardio workouts.”

Fortunately, a new breed of fitness apps is emerging that uses the accelerometer access enabled by the recently released watchOS 2 to track strength and flexibility workouts more effectively.
