Common Mistakes
- •Not using the full range of motion
- •Using momentum instead of controlled muscle tension
- •Not maintaining proper form throughout the movement
Safety Tips
- •Always warm up properly before attempting this exercise
- •Stop immediately if you feel sharp or joint pain
- •Keep your core engaged to protect your lower back
Variations
- •Perform one arm at a time to fix strength imbalances
- •Try a neutral grip to reduce shoulder strain
- •Increase the range of motion by using a bench that allows a deeper stretch
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)
- •Try the same exercise with a barbell instead of dumbbells to handle heavier loads
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
- •Perform with just the bar or light dumbbells to groove the movement pattern
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
- Implement progressive overload by tracking every session and adding small increments
- Breathe deliberately — exhale during the hardest part of the movement
- Warm up with lighter sets of the same exercise to prime the nervous system
