With much of the world unable to go to the gym at the moment due to coronavirus isolation measures, smartphone fitness apps and online classes are here to help.

There are many options to choose from. Some are free while others offer subscriptions to unlock extra content. Some focus on specific forms of exercise, while others aim to cover as broad a range as possible. But what they all share in common right now, is they offer a simple way to exercise and stay fit while unable to leave your home.

Many ask that you have little or no exercise equipment, making do with your own body weight to work out, plus the occasional helping hand from a step, exercise map, or gym weights.

Generally speaking, there are two routes you can take here. One is to use an app which has live or pre-recorded sessions led by a personal trainer. These are great for those who are new to exercise and aren't sure what's best to do, or who work best when they have a professional telling them what to do and offering words of encouragement.

The other side of this is to use an app that walks you through each exercise, but in a simpler and less personal way. These apps tend to show you what to do, then audibly alert you when it's time to switch to something else, or take a short break.

Here are some home fitness app suggestions to get you started:

Seven - Available for iOS and Android - Free plus in-app purchases

Seven app encourages users to exercise for just seven minutes a dayPerigee

The app offers some exercises for free, but opens up when you subscribe to the 7 Club, which costs $9.99 a month or $59.99 for the entire year. With that, users get access to personalized workout plans and over 200 exercises, plus support and guidance from the app's own personal trainer.

The UI is simple to navigate and lets you plan your weeks based on what you want to achieve, and what types of exercise you fancy doing each day. As with many fitness apps, there is an awards and achievements system, plus a community to make exercise more social. We would normally stray away from the latter, but given we're all stuck inside for the foreseeable future, social interaction through a fitness app is no bad thing.
