Dr. Muscle vs Fitbod
Dr. Muscle leads with adaptivity: auto-adjusts sets/reps/weight each session based on feedback, claims development by an exercise-science PhD based on elite-athlete research, official pricing around $49/month or $399.99/year (some channels list around $20/month - conflicting figures), limited free version after 14-day trial. Fitbod is algorithm-based workout planning: generates daily plans from training history, equipment and muscle recovery, 1,500+ exercise library, muscle-recovery heatmap, about $15.99/month or $95.99/year, 7-day trial, no human coaches, no nutrition guidance. We ran no hands-on test and don't judge muscle-building results. Serious lifters wanting in-workout auto-adjustment look at Dr. Muscle (verify the real checkout price first); self-directed trainers wanting an affordable reliable planning tool look at Fitbod.
