Exercise guide

Cheat Curl

  • Intermediate
  • Isolation
  • Rep-based
  • Shoulders
  • Upper arms

The cheat curl uses controlled momentum from the hips and legs to bypass the sticking point, allowing you to overload the biceps with heavier weights than a strict curl. This variation specifically targets eccentric strength and muscle hypertrophy by forcing the biceps to control a heavy load on the way down.

Setup

  1. Stand with your feet shoulder-width apart, holding a barbell with a shoulder-width underhand (supinated) grip.
  2. Start with the bar resting against your upper thighs and your arms fully extended.
  3. Engage your core, pull your shoulder blades back, and maintain a slight bend in your knees.

How to do it

  1. Perform a quick, shallow hinge at the hips, then explosively drive your hips forward to create upward momentum.
  2. Simultaneously curl the bar toward your shoulders, exhaling as you use the momentum to move the heavy weight through the full range of motion.
  3. Squeeze your biceps hard at the top of the movement for a brief moment.
  4. Inhale as you slowly lower the bar back to the starting position over a 3-4 second count, resisting the weight entirely with your biceps.

Form checklist

  • Use the hips for momentum, not the lower back for excessive arching.
  • Keep your elbows tucked near your sides rather than letting them flare or swing too far forward.
  • Ensure the 'cheat' only happens on the way up; the lowering phase must be slow and controlled.
  • Keep your feet planted firmly to maintain a stable base during the hip drive.

Pro tips

  • The 'cheat' is a tool to overload the eccentric; if you aren't controlling the weight on the way down, you are losing the primary benefit of the exercise.
  • Think of your glutes and hamstrings as the engine that starts the lift, then let your biceps take over the steering.

Make it harder

  • Increase the weight to 110% of your strict curl 1-rep max to maximize eccentric mechanical tension.
  • Add a 5-second eccentric count to every rep to increase time under tension.
