AI for Fitness: Free Tools to Build Workouts and Track Progress

✅ Find out 10 ways AI can help you budget better here!

Getting fit doesn’t have to mean paying for expensive personal trainers or fitness apps. Thanks to AI, there are now free tools that can help you design workouts, track your progress, and stay motivated – all without spending a penny. Here are some of the best ways to use AI to level up your fitness on a budget.

1. ChatGPT for Custom Workouts

You can use ChatGPT to create personalised workout routines based on your goals, fitness level, and equipment. Whether you want a 20-minute home workout or a full gym plan, it can generate one in seconds.

💡 Tip: Be specific – include how many days a week you want to train, what equipment you have, and your goals (e.g. strength, weight loss, flexibility).

2. Fitbod (Free Trial)

Fitbod is an AI-powered app that creates workout plans tailored to your past training and recovery. While the full version is paid, the free trial gives you a chance to test personalised routines.

💡 Tip: Use the free trial to gather a few different plans, then reuse them even after it ends.

3. Aaptiv Coach (Free Tier)

Aaptiv Coach uses AI to recommend daily workouts and fitness challenges based on your activity levels. The free tier gives you access to bodyweight workouts you can do at home.

💡 Tip: Great for beginners who want a bit of structure without paying for premium fitness apps.

4. MyFitnessPal with AI Suggestions

While MyFitnessPal is mainly known for calorie tracking, its AI now suggests workouts and healthy habit tips based on your logged activity and goals.

💡 Tip: Use it alongside a free pedometer or smartwatch app to keep your steps and workouts synced.

5. YouTube + AI Recommendations

YouTube’s algorithm works like an AI trainer – once you start searching for fitness routines, it will keep recommending similar workouts (HIIT, yoga, weights, etc.). This means you can build a free video workout library personalised to your style.

💡 Tip: Subscribe to a few trainers you like, and YouTube will do the rest.

6. Strava with AI-Powered Insights

Strava has built-in AI analysis for running and cycling. It tracks your pace, effort, and improvements over time – perfect for outdoor fitness lovers.

💡 Tip: Use the free plan – it’s already packed with enough insights to keep you progressing.

Summary: AI can’t replace the hard work you put into your fitness, but it can make things simpler, smarter, and much cheaper. From custom workout plans to progress tracking, these free tools mean you don’t need to splash out on a personal trainer to stay on track.
