Why your biceps feel more worked than your triceps
Electromyography Activity of Biceps and Triceps Muscle in Concentration Curl and Kickback Exercise among Young Healthy Individual

When you do arm exercises like curls and kickbacks, your biceps light up more than your triceps—even when they're not the main muscle being used.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

When performing resistance exercises, the biceps muscle shows greater electrical activity than the triceps muscle, whether it is the main muscle moving the weight or the one resisting the movement, in healthy adults aged 20 to 30.
During weightlifting, the biceps muscle often shows higher electrical activity than the triceps, even when the biceps is not the primary mover, suggesting that the specific exercise being performed has a greater influence on muscle activation than whether the muscle is pushing or pulling.
In resistance exercises, the biceps muscle shows greater electrical activity than the triceps muscle, whether it is doing the main work or opposing the movement, in healthy young adults aged 20–30.
During resistance exercises like concentration curls and kickbacks, the biceps muscle consistently shows higher levels of electrical activity than the triceps, regardless of whether it is the main muscle moving the weight or the opposing muscle.
Surface electromyography can measure and distinguish the highest levels of muscle activity in the biceps and triceps when performing exercises like concentration curls and kickbacks in healthy young adults.
