Negative curls focus exclusively on the eccentric (lowering) phase using heavier weight than you could lift concentrically. You use assistance—either your other hand, a partner, or momentum—to get the weight to the top, then lower it as slowly as possible. This eccentric overload creates significant muscle damage that drives adaptation.
When to use it
Use sparingly to break plateaus or as intensity technique.
Who it's for
Advanced lifters looking for eccentric overload.
Lower the weight over 4-6 seconds, fighting gravity the entire way. Do not let it fall. Use 20-40% more weight than your normal curl weight. These are extremely fatiguing, so limit total sets and allow extra recovery time.
Also targets: Forearms, Brachialis

Use heavier weight than normal curls.
Use both hands or assistance to lift weight to top.
Remove assistance and hold weight with one arm.
Lower the weight as slowly as possible (4-6 seconds).
Fight gravity throughout the entire descent.
Repeat for desired reps per arm.
Eccentric focus creates more muscle damage for growth.
Use 20-40% more weight than normal curls.
Can be very effective for breaking plateaus.
Use negative curls sparingly to break through plateaus or as an advanced intensity technique. They cause significant muscle damage, so limit to once per week and allow 48-72 hours recovery before training biceps again.
Lowering too fast - defeats purpose.
Rushing through the Negative Curl makes it easier to lose position and harder to keep tension on your Biceps brachii. Slow down enough to control both the lifting and lowering portions of each rep.
Using too much weight - cant control.
Loading more weight than you can control on the Negative Curl often creates compensations that shift work away from your Biceps brachii. Reduce the load until each rep follows the intended path.
Doing too many sets - very fatiguing.
On an upper-body pulling movement like the Negative Curl, this mistake can shift work away from your Biceps brachii. Keep your torso stable and guide the load through the intended pulling path.
Advanced lifters looking for eccentric overload.
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 2-3 sets of 5-6 reps per arm. Rest 2-3 minutes.
This is one example of how Negative Curl could sit inside a complete workout. Your plan may use different movements after Ely checks your assessment.
