About interval training
A 1-minute work / 30-second rest interval (2:1 ratio) is a workhorse for most strength-conditioning combinations. Long enough for compound exercises, short enough to keep heart rate elevated.
Benefits
- ·Suits compound strength exercises (deadlifts, squats, presses)
- ·Maintains elevated heart rate without burning out
- ·2:1 work-to-rest is the classic CrossFit-style protocol
- ·Total session at 8-12 rounds = solid 12-15 min workout
- ·Mental durability — 1 minute under load builds grit
How the protocol works
60 seconds of work, 30 seconds of rest. Pick a challenging exercise — kettlebell swings, thrusters, rowing, burpees. The 2:1 ratio creates accumulating fatigue so each round gets harder.
Endurance research finds 2:1 work-to-rest as the optimal ratio for sustained intensity over multiple rounds. CrossFit and most boot-camp programs default to this format for compound movements.
Who uses it?
CrossFit athletes, intermediate-to-advanced fitness levels. Good for kettlebell, barbell, or rower-based workouts.
