What does HIT stand for in strength training?

High-Intensity Training — strength work with weights, taken to momentary muscular failure. Popularised by Arthur Jones (Nautilus) in the 1970s.

What does HIIT stand for?

High-Intensity Interval Training — short bursts of intense cardio interspersed with rest, popularised in the 2010s.

Can you do HIT and HIIT together?

You can, but they compete for recovery. HIT already demands significant recovery; adding HIIT on top can interfere with strength adaptation. Most HIT trainees keep conditioning separate and minimal.

HIT vs HIIT — what's the difference?

HIT and HIIT share four letters and almost nothing else. One is strength training with weights. The other is cardiovascular intervals. Confusing them is the most common mistake in this corner of fitness.

HIT — strength, weights, failure

HIT (High-Intensity Training) is a form of strength training. You move weights through a controlled range of motion until you reach momentary muscular failure — the point where no further controlled repetition is possible. It is brief, hard, and infrequent. Read the full HIT explainer →

HIIT — cardio, intervals, heart rate

HIIT (High-Intensity Interval Training) is cardiovascular exercise. You alternate short bursts of intense cardio — sprints, bike sprints, burpees — with brief recovery periods. It targets conditioning and heart rate, not muscular strength.

The key differences

Modality: HIT uses weights and machines; HIIT uses bodyweight or cardio movements. Goal: HIT builds strength and muscle; HIIT builds conditioning. Intensity marker: HIT ends a set at muscular failure; HIIT ends an interval at near-maximal heart rate. Recovery: both demand recovery, but HIT's fatigue is primarily muscular and neural.

Why the confusion matters

If you search for a "HIT app" expecting a strength logbook, you'll be shown HIIT timers. Failure Point is a HIT logbook — it tracks one set to failure with weights, calculates progression, and prescribes rest. It is not a HIIT timer. See how one-set-to-failure works → Or read what HIT is → or the HIT glossary entry.

Failure Point is a training logbook, not medical advice. Training to failure carries injury risk.
