What is a good work-to-rest ratio for HIIT?

2:1 (e.g. 30s work / 15s rest) is a solid intermediate default. Beginners often do 1:1 or 1:2 (more rest), while advanced athletes push toward 3:1. The generator nudges the ratio with your level setting.

How many rounds will I get?

Roughly total seconds ÷ (work + rest). A 20-minute session at 30s/15s gives ~26 rounds. The tool always shows the exact count after generating.

Will the same exercise repeat?

Yes — the pool is rotated. With 26 rounds and a 15-move bodyweight pool, each move appears about twice. That’s by design: HIIT works best when you can stay safe with a known movement under fatigue.

Is HIIT safe for beginners?

Beginners should start with shorter sessions (10–15 minutes) and longer rests. Skip plyometric moves if you have knee, hip, or back issues, and consult a professional if you’re unsure.

Does the plan persist between visits?

Yes. Your inputs and last generated plan are stored in your browser on this device. Use Reset to clear them.

Should I warm up first?

Always. 5 minutes of easy cardio plus joint mobility cuts injury risk dramatically. The HIIT plan itself does not include a warm-up.

About this hiit workout generator

The HIIT workout generator turns four inputs — total minutes, work seconds, rest seconds, and level — into a fully-laid-out round-by-round plan from a bundled exercise pool. The pool changes with equipment: bodyweight (15 moves including burpees, mountain climbers, squat jumps), dumbbells (10 moves like thrusters and renegade rows), or a mixed bank. The number of rounds is computed as floor(totalSeconds ÷ (work + rest)), and intervals shift with level: beginners lose 5 seconds of work and gain 5 seconds of rest, advanced lifters do the reverse.

A worked example: 20 minutes total, 30s work, 15s rest, intermediate, bodyweight. The tool computes 20 × 60 ÷ 45 = 26 rounds and cycles through the bodyweight pool, so you get Jumping Jacks, High Knees, Burpees, Mountain Climbers, Push-Ups, Squat Jumps, Plank Shoulder Taps, and so on, each at 30s work / 15s rest. The actual time displayed adjusts to the rounded number of rounds. Everything saves to your device so you can return to the same plan tomorrow.
