Mistakes to avoid with a free fitness app
1. Switching apps every month
The best app is the one you'll use regularly. Give yourself at least 4 weeks to build your routine.
2. Ignoring customization
Even the best apps only work if you adapt workouts to your level. Start easy, progress gradually.
3. Not combining with good nutrition
A free fitness app isn't enough on its own. You also need to eat correctly. Check our caloric deficit guide for the basics.
4. Expecting results too fast
Visible results take 4 to 8 weeks. Be patient and consistent.
