Stair Climb Intervals 20 min
Eight hard flights with walk-down recovery — a high-intensity cardio session using stairs you already pass every day.
Eight hard flights of stairs with a walk-down recovery gets you near threshold heart rate faster than any flat-ground effort, and every office building already has the equipment. Twenty minutes, high intensity, one piece of infrastructure you already pass every day.
The session at a glance
- Focus: cardio
- Intensity: high
- Duration: 20 minutes
- Equipment: stairs
The protocol
- Warm-up — 5 min. Two easy flights up and down.
- Hard flight — 8 rounds. Climb briskly, one step at a time, hand off the rail.
- Recovery. Walk down at an easy pace between rounds — the descent is the rest.
- Cool-down walk — 5 min.
Why this works
- Fast route to threshold heart rate. The vertical load of stair climbing raises heart rate faster than equivalent flat-ground running.
- Built-in recovery. The walk-down is genuinely restful, which is what lets eight hard efforts fit inside 20 minutes.
- No equipment to find. A stairwell most people already pass through daily is the entire session.
How to scale it
- Start with 4-5 rounds and add a round as the descent recovery starts to feel too easy.
- Keep a hand on the rail on the way up until footing on the specific stairwell is familiar.
- On a joint-sensitive day, walk the ascent briskly rather than climbing, and keep the round count the same.
