When most of us buy a gym membership, we imagine having the time and discipline for building muscle or losing weight. Unfortunately, most of us know things usually don’t work out that way.

Nowadays, it’s possible to get a comprehensive workout without a gym, or even any equipment. Bodyweight training has been growing in popularity for years. That’s partly because using your own weight as resistance is economical and effective. But it’s also because smartphones offer a convenient and portable “virtual coach,” thanks to a new class of workout app.

With New Year’s Eve a distant memory, your resolutions for 2017 should now be well underway. To help keep up your good work, here’s Week 3 of our CultFit Home Workout. (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 is required. It’s a great way to get started with your fitness journey — and it only takes 10 minutes a day.

Fitness is not just about walking, running and cycling, despite what your Apple Watch may have you believe. Strength training is also important. Without it, your fitness routine is like a one-hand clap. Whether you are aiming for a ripped beach body or just to improve your overall health, you need to lift some weights.

Apple Watch and iPhone do not offer built-in support for strength training, but the good news is there are plenty of third-party apps that can plug the gap. Apple Watch weightlifting apps can help in three ways: by telling you what to do; showing you how to do it; and keeping a log of what you’ve done.

Apple’s fitness apps are surprisingly limited given that is a core selling point of Apple Watch. Even basic features like mapping runs and challenging friends are currently missing. And from what we’ve seen so far, watchOS 2 won’t address these shortcomings.

Here’s my wish list of 10 things I’d like to see Apple do to get its fitness apps in shape.
