Breathing
Exhale as you pull the weight toward your body, inhale as you extend back to the start.
Common Mistakes
- •Not maintaining proper form throughout the movement
- •Rushing through reps instead of using a controlled tempo
- •Holding your breath during the movement
Safety Tips
- •Start with a weight you can control, not your one-rep max
- •Maintain proper posture and alignment throughout the movement
- •Use a spotter or safety racks when lifting heavy
Variations
- •Try a deficit version to increase the range of motion
- •Add a pause at the bottom to eliminate momentum
- •Increase intensity by elevating your feet
Alternatives
- •Choose another exercise that targets the abdominals
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
- •Use an assisted version (bands, partner, or machine) to reduce load
- •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
- Stay tight throughout — brace your core before every single rep
- 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
