Explained

What this calculator does for you

A good warmup primes the CNS, joints and technique for your work weight — without fatiguing you before the first work set.

We ramp in 5 sets: empty bar, 50 %, 70 %, 85 %, ~92 % — each set with fewer reps.

Stores stay full, technique gets grooved and your first work set isn't your first heavy set.

Science

Scientific background

Specific warmups with the same lift measurably improve work-set output (Fradkin et al. 2010).

Static stretching before heavy lifts reduces max strength — avoid it right before the main lift.

Warmup reps should drop as load rises — otherwise you build unnecessary fatigue.

Examples

Practical examples

Working weight 100 kg

20 kg × 8–10, 50 kg × 5, 70 kg × 3, 85 kg × 2, 92.5 kg × 1, then 100 kg.

Working weight 60 kg

20 kg × 8–10, 30 kg × 5, 42.5 kg × 3, 50 kg × 2, 55 kg × 1, then 60 kg.

Avoid these

Common mistakes

  • 01Skipping the warmup. Saves 5 minutes — costs joints over time.
  • 02Too many warmup reps. You enter work sets already tired.
  • 03Jumping straight to heavy without a ramp. CNS and joints aren't ready.

Recommendations

Further recommendations

  • 01Plan the warmup in your program — not as an extra, but as part of the lift.
  • 02Ramp only for the heaviest lift of the session.
  • 03If sore or stiff: longer general warmup, lower starting load.

FAQ

Frequently asked questions

Should I ramp for every exercise?
Only for the heaviest lift in a muscle group. Follow-up lifts usually need 1–2 warmup sets.
Rest between warmup sets?
30–90 seconds at lower percentages, 2–3 minutes before the 92 % single.
Cardio first?
5 minutes of general warmup (row, bike) is fine. Longer cardio costs glycogen needed for work sets.
