The prompt

Copy the complete prompt (it wraps the request below so the AI returns a clean, runnable session).

Write me a 20-minute lower-body HIIT conditioning session. Use 6 to 8 rounds of 30 seconds hard work — choices like fast bodyweight squats, jump squats (or step-backs to keep it lower impact), kettlebell swings, and reverse lunges — with 60 to 90 seconds easy recovery between rounds. Keep the effort hard but controlled. Build it as timed rounds and list each move in order with its work and rest in seconds.

Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Interval conditioning improves cardio fitness and helps reduce body fat, and works well on a day separate from heavy leg training. Keep the effort genuinely hard but scalable.
