2. Yoga Studio (£1.99)

Yoga Studio
Yoga isn't the easiest thing to get to grips with on your own, but Yoga Studio does a good job of helping you out.
With advice and instructions for over 280 poses you'll be doing the downward-facing dog and feathered peacock in no time.
But not only does Yoga Studio teach you the basics, it also includes 30 yoga classes with HD video and lets you easily create custom classes.
So whether you're a beginner or have been practising yoga for years, Yoga Studio can help.

3. Cyclemeter GPS (£2.99)

There are loads of running apps out there, but the selection of cycling apps is rather smaller. Thankfully there are still some great ones, such as Cyclemeter GPS.
You can use it to time your rides, track how far you've ridden, view route maps, see graphs of your performance over time and more. With the help of additional sensors it can also record your heart rate, bike speed, bike cadence and bike power.
Announcements will let you know how you're doing while you ride, you can compete against previous times and even configure interval training, zones and targets. In other words Cyclemeter GPS is about as comprehensive as you could hope a cycling app would be.

4. Runtastic Pro (£2.99)

Runtastic Pro
Runtastic Pro is a full featured running app, allowing you to track your speed, distance, elevation and burnt calories while running.
But those are just the basics, it also lets you set up training goals, create and find routes, view graphs and historical data of your workouts and control your music from the app.
You can also get audio feedback for every mile or km that you run and manually enter other workouts so that you can keep track of all of your exercise from one app.
It can even be synced with MyFitnessPal, so if you already use that you can easily add your run data to it.

5. Fitocracy (free)

Fitocracy does its utmost to make fitness fun. At its core it's designed to let you log workouts so you can track your progress.
But to keep you motivated it incorporates points that can be earned, achievements that can be unlocked and quests that can be beaten.
Essentially it turns fitness into an RPG and it works pretty well, almost making it feel more like you're playing a game than working out.
Add to that an attractive interface and a supportive community and Fitocracy could be just what you need to stay motivated when the exercising itself starts to feel like a chore.

6. Moves (£1.99)

Moves
Moves is a pedometer for your phone, 
but it's also so much more than that. 
It's got a step counter that can track 
your walking and running and it's 
designed to be left on all day, so in 
other words it does the same job as a
dedicated fitness tracker such as Fitbit 
Force.

But Moves also lets you plot your routes on a map, see how many calories you've burned and even view your day as a timeline, seeing where you were when and for how long.
While you'll certainly notice its impact on your battery it's been optimised to be as light on resources as possible, so you should still be able to get at least a day out of your iPhone with Moves running in the background.


7. MyFitnessPal Calorie Counter & Diet Tracker (free)

As the name suggests, MyFitnessPal is a calorie counter and diet tracker, though it can also be used to keep track of how much exercise you do.
With over 3 million foods in its database it's likely to have the things you eat and if it doesn't you can easily create a new entry.
Logging exercise is just as easy and on top of tracking calories you can also track fat, carbohydrate, sugar and more.
Then once you've been using the app for a while you can view charts of your calorie consumption and weight changes over time, to see just how much progress you're making.

8. 7 Minute Workout Challenge (£1.49)

7 Minute Workout Challenge
Half the battle with getting fit is finding time to actually exercise, but 7 Minute Workout Challenge essentially removes that part of the equation, by giving you a simple workout that only takes around 7 minutes and can be done without any specialist equipment.
It uses high intensity interval training across 12 different exercises and is designed to boost your metabolism, making it far more effective than a 7 minute workout has any right to be.
The workout can be provided by a male or female trainer that will guide you by audio, video, images and text.
On top of the workout itself the app also includes a weight and activity tracker and the ability to unlock achievements.

9. Zombies, Run! (£2.49)

Let's face it, zombies just aren't that scary any more. They've been overdone and it almost seems like you can't leave your house without some zombie themed thing getting in your face.
But when a horde of them are chasing you that's still likely to be motivation enough to pick up the pace.
Zombies, Run!
That's the thought behind 'Zombies, Run!', an app which combines the bread and butter of run tracking (distance, time etc) with the constant threat of becoming food for the undead.
That threat is delivered via audio as you run and if you somehow need even more motivation there's also a fairly lengthy story and specific mission goals which you can work your way through by working out.

10. Full Fitness: Exercise Workout Trainer (£1.49)

Full Fitness: Exercise Workout Trainer
Full Fitness serves two main purposes. The first is teaching you new exercises.
There are hundreds included in the app with images and text instructions for all of them, video instructions for some and new exercises being added all the time.
The second purpose is to log workouts and motivate you to keep at it. There are 30 routines included with the app, along with the option to create your own, so you can keep things varied and interesting.
Plus if you're working towards a specific goal or want to target a specific muscle or body part, Full Fitness has you covered there too, as the exercises are all labelled accordingly.
