If you need help in getting started with an exercise programme, for example, focused on muscle strength and endurance, you don’t have to hire a trainer. There are a very wide variety of fitness apps that are available. They present hundreds of exercises, with clear photos or videos and instructions for how to do each exercise safely and correctly. You can browse by category or muscle group and follow a workout checklist with a suggested routine or create your own custom set of exercises. They also let you log and chart your progress in a journal with entry screens tailored for each exercise. The right fitness app may not be a magic wand but is certainly a fantastic ally in your weight-loss journey.
