Sets, reps and RIR

Sets3 to 4
Reps10 to 15
RIR0 to 2

Single-joint work responds to reps and time under tension more than to heavy load.

RIR means reps in reserve: how many you could still have done when you racked it. RIR 2 is two short of failure.

Muscles worked

Primary: Triceps.

Estimate your one-rep max

Epley's formula, from a set you have actually done. It is an estimate, and it drifts above eight reps, so keep the input between one and twelve.
