Exercise Snacks
1-5 min bursts of activity throughout the day — stair climbs, push-ups, squats. Studies show 3-4 daily 'exercise snacks' reduce mortality by 40% in non-exercisers.
Dosage & Timing
Evidence Strength
4/5 — StrongRecent large-scale wearable studies (UK Biobank) show strong mortality benefit from vigorous intermittent lifestyle physical activity.
Overview
Brief bouts of vigorous activity (1-5 minutes) scattered throughout the day. Examples: stair sprints, air squats, push-ups, or brisk walking intervals. Research shows these micro-workouts reduce all-cause mortality even in people who don't formally exercise.
How To Do It
Set reminders
Every 60-90 minutes, do a brief bout of movement.
Choose activities
Stair sprints, push-ups, air squats, jumping jacks, or a brisk 2-min walk.
Make it vigorous
Brief but intense enough to get breathing hard.
The Evidence
Each claim is linked to its source study. Confidence reflects the study design — systematic reviews and RCTs rank highest.

Exercise Snack Ladder
Insert 1-3 minute bouts of stairs, brisk walking, or bodyweight movement into sedentary days.
Resistance Training (3x/week)
Progressive overload strength training 3x/week. The single most protective exercise against age-related decline in muscle, bone, and metabolic health.
Grip Strength Training
Train grip 2-3x/week with dead hangs, farmer carries, and crush exercises. Grip strength is a top biomarker for longevity and functional independence.
Daily Mobility Routine
10-15 min daily mobility work targeting hips, thoracic spine, shoulders, and ankles. Prevents injury, improves movement quality, and maintains functional capacity.
