Question: I need a convenient and affordable way to get in shape without a gym membership or personal trainer - are there any online fitness services that can help?

If you want to get in shape but don't have a gym membership or personal trainer, there are a lot of online fitness services that can help. One interesting option is Body Scan, an AI-powered fitness service that generates a workout plan based on a full-body selfie. It offers a detailed breakdown of body fat and lean mass percentages, daily caloric intake and macronutrient ratios. The service also offers video workouts based on your body and goals. Body Scan prioritizes user privacy and security, and it's a useful, data-driven approach to fitness that's free.

Another good option is FitnessAI, which uses artificial intelligence to create a personalized weightlifting program. It optimizes sets, reps and weight for each exercise, and after 30 days, you can expect to lift 20% more weight on average. The service tracks progress, logs workouts and even lets you chat in app with real trainers for advice, so it's a good alternative to a personal trainer.

If you want to incorporate genetic and biometric data, Alter could be a good fit. The service combines genetic data from DNA tests with biometric data from wearables to create personalized workout plans, recovery plans and nutrition advice. It offers elite coaches, DNA-based nutrition plans and real-time heart rate monitoring during workouts, so it's a good option for those who want a more holistic fitness approach at $99 per month.

Last, Ardor offers personalized workouts based on your fitness needs, schedule, available equipment and goals. It offers adaptive programs that change as you progress, personal challenges and the ability to share workouts with friends. With a relatively low subscription price of $5.99 per month, Ardor is a good option for those who want a flexible and rewarding fitness experience.
