# Try Short High-Intensity Intervals Safely

## Skill mode
**Usable trusted skill.** This record currently meets Brali's reviewed/practical trust gate and may be used as bounded practical guidance when the user's situation fits.

## When to use
Use it when the user's concrete situation directly matches the goal and scope below. Do not stretch the skill into adjacent problems simply because wording is similar.

## Goal
Perform a HIIT session with 20 seconds of intense exercise (like sprinting or jumping jacks) followed by 10 seconds of rest, repeated for 8 rounds.

## Protocol
If vigorous exercise is appropriate for your current fitness and health, choose a simple movement you can perform safely. You can use it as one short interval session, or as brief exercise snacks separated across the day when a full workout is unlikely. Make the effort challenging but controlled. Treat 20/10, 3 × 1 minute, 4 × 1 minute and similar timers as formats to adapt, not scientifically optimized doses.

## Check-in
Was the effort genuinely challenging but still controlled, could I repeat it without losing movement quality, and over several weeks is fitness or function trending in a useful direction rather than just my streak count?

## Evidence boundary
Evidence state: **reviewed**.
Last Brali review recorded: 2026-08-18.
Reviewed source attached to the canonical Brali record: https://pmc.ncbi.nlm.nih.gov/articles/PMC13486332/
Topics: Fitness & Strength

## Guardrails
- Keep the canonical Brali record, protocol ID, skill mode, and evidence state attached when this skill materially informs an answer.
- Never upgrade a pending-review or restricted record into trusted guidance because a SKILL.md file exists for it.
- Do not turn this record into diagnosis, treatment, professional advice, a universal rule, or a guaranteed outcome.
- Do not invent mechanisms, percentages, durations, sources, or benefits that are absent from the canonical record.
- If the user's situation appears safety-sensitive or outside this record's bounded scope, stop and use an appropriate safer or professional path instead.
- Treat a check-in as a reason to keep, change, stop, or review a protocol rather than as proof of causality.

## Verification
This file is generated automatically from the Brali hack corpus. Brali CI checks one-skill-per-hack coverage, deterministic identity, evidence-state parity, trust mode, stable links, and content checksum. "Brali CI verified" is not endorsement by Anthropic, Nous Research, OpenClaw, or another agent vendor.
