Breathing
Exhale as you push the weight away from your body, inhale deeply as you return to the starting position.
Common Mistakes
- •Using momentum instead of controlled muscle tension
- •Not maintaining proper form throughout the movement
- •Rushing through reps instead of using a controlled tempo
Safety Tips
- •Maintain proper posture and alignment throughout the movement
- •Use a spotter or safety racks when lifting heavy
- •Always warm up properly before attempting this exercise
Variations
- •Adjust the pulley height to target different fibers
- •Use a slow, controlled tempo to prevent the stack from clanking
- •Try single-arm work for unilateral focus
Alternatives
- •Choose another exercise that targets the triceps
Progressions
- •Master the basic form with bodyweight before adding external load
- •Increase the weight by 5-10% once you can complete all reps with clean form
- •Slow down the eccentric (lowering) phase to 3-4 seconds
- •Reduce rest periods between sets to increase workout density
- •Add an extra set or rep each week (progressive overload)
Regressions
- •Reduce the weight to focus strictly on technique
- •Decrease the range of motion if you feel joint discomfort
- •Increase rest intervals to ensure full recovery between sets
Beginner Tips
- •Master proper form before increasing weight
- •Focus on slow, controlled movements — don't chase speed
- •Start with 2-3 sets of 10-12 reps to build a solid foundation
- •Record yourself to check your form
Pro Tips
- Focus on the mind-muscle connection — consciously squeeze the target muscle at the peak of each rep
- Use a 2-1-3 tempo (2 seconds up, 1 second pause, 3 seconds down) to maximise time under tension
- Implement progressive overload by tracking every session and adding small increments
