❗ Yes — For:
- First exercise of every new muscle group, even if it’s not the first movement of your workout
- All major compound lifts (squat, deadlift, bench press, overhead press, barbell rows, etc.)
- Any movement involving multiple joints, heavier loads, or greater skill demand
Each muscle group and movement pattern deserves its own warm-up prep, especially for big lifts where technique and joint stability are critical. Your nervous system and joints must be “dialed in” specifically for the task ahead.
✅ Minimal Warm-Up — For:
- Second or third exercise for the same muscle group
Example: After flat bench press, your pecs, triceps, and shoulders are already warm. For incline dumbbell press, you may only need 1 light set to groove the new movement pattern.
Goal: Rehearse the motion, assess joint readiness, then start working sets.
- Stable exercises on machines
These require less coordination demands
Goal: Rehearse the motion, assess joint readiness, then start working sets.
- Isolation exercises (e.g., lateral raises, curls, triceps extensions, leg curls)
These typically involve:
- Lower loads
- Simpler joint mechanics
- Smaller muscle groups
Warm-up sets can still be smart — and sometimes necessary — especially if:
- You’re lifting heavier weights (e.g., heavy dumbbell curls)
- You’re using strict form with high intensity (close to failure)
- You have sensitive joints or prior injuries (like shoulders or elbows)
🔹 Recommendation:
For most isolation exercises, perform 1–2 warm-up sets at 60–80% of your working weight for 4–6 reps. This wakes up the muscles, checks your technique, and protects your joints — especially important for strong or advanced lifters.
Rule of thumb:
- New muscle group = full warm-up progression
- Same muscle group = 1 lighter set is usually enough
- Isolation = 1–2 warm-up sets
🔍 Quick tip: If you’re doing an exercise for a muscle that has been secondarily worked, for example, bicep curls after rows or pull-ups, your biceps are already pre-activated. A single light warm-up set is all you need.
