Is there any good iPhone app that helps with fitness and nutrition?

I have an iPhone and iPod and I want to know is there any good fitness and nutrition apps from App Store. There are so many and I'm not sure what ones to download. They can be paid and free and they can be in the uk store and the us store. Please help! I would like the apps to make me lose weight and gain muscle. Also are there any personal trainer apps?

I use fitness buddy and lose it. Rede good because it shows you exercises and food and you can track everything

Try MyFitnessPal. Shows maintenance calories, calories you need to lose a pound a week, 2 pounds per week, etc.

You can also input cardio exercises that'll subtract your total calories. Same with gym exercises.

Pretty good stuff. They have a wide food Database for calorie tracking too.

  • How to tune into Lifetime Fitness TV stations? I have an iPhone and I want to listen to the TV shows that they have going on the various screens. Each TV has a small sign under it saying what station to tune into. Is this possible with an iPhone? I have download FM radio apps but its all preset stations.
