Rest between sets, in minutes. In supersets (A1, A2) you do the exercises back to back: the short pause goes between them, and the round's rest comes after the last one.

How to progress

Add reps within the range at the indicated RIR; once all sets hit the top of the range, go up to the smallest available weight.

  • RIR 2 on compound lifts
  • RIR 1 on accessories

RIR is the reps you have left in reserve: with RIR 2 you end the set when you could still do 2 more.

Frequently asked questions

How long is the Arm specialization routine?

It's designed for 6 weeks, with 4 sessions of about 65 minutes a week.

How many sets does each muscle get per week?

As the primary muscle, 12 sets for the biceps, 12 sets for the triceps, and 11 sets for the quads per week. That's 59 sets a week in total.

What is a superset?

Two or more exercises in a row, with almost no rest between them: you rest when the round is done. In the table they're marked A1, A2. It saves time without cutting sets.

What is RIR?

The reps you have left in reserve when you finish a set: with RIR 2 you stop when you could still do 2 more. In this routine it goes from RIR 1 to RIR 2.

What do I need to do it?

You do it in a gym, with this equipment: barbell, eZ bar, dumbbells, cable machine, machine, bench, and rack.
