Build toward 20 continuous minutes
Choose brisk walking or easy running at a sustainable pace. Start with short active intervals and recovery walks, then gradually build longer continuous efforts. Running is optional, and the intervals can also be adapted for a stationary bike or rowing machine.
What is inside
Phase 1: build your base with short intervals and walking recovery.
Phase 2: build toward 20 continuous minutes of activity.
Two cardio sessions per week, planned around your other training.
Clear readiness checks, shorter starting options, and guidance on repeating weeks.
Safety guidelines covering medical concerns, running impact, footwear, surfaces, heat, and recovery.
Start at your level
For walking or running, you should first be able to comfortably complete a 20-minute walk. Read all instructions and safety guidelines before beginning. The weeks are flexible stages, so repeat them as needed and use a pace where you can still talk in sentences.
This guide provides general fitness education for independent exercise. It is not medical advice, an individual exercise prescription, or supervised training. No program can eliminate injury risk or guarantee results.
