Why do almost all fitness apps still pretend everyone is a 22-year-old bodybuilder?

When I had an emergency heart stent at 42, I had to rebuild my daily health from zero. Every app I opened pushed the same playbook: extreme calorie restriction, 90-minute punishing workouts, and zero attention to sleep, joint recovery, or daily life stress.

For anyone balancing a demanding job, family, and real-world fatigue:

What is the biggest blind spot modern fitness apps have for adults over 35? Is it unrealistic workout lengths, complex macro logging, or something else?

Would love to hear what has actually worked for you.
