Workout Information

Description:

This workout routine is designed to primarily build and strengthen the biceps brachii, brachialis, and brachioradialis. All three muscles contribute to elbow flexion, but their relative involvement shifts with forearm rotation — the supinated (palms-up) grip maximizes biceps activation, while the neutral (palms-facing) grip shifts emphasis toward the brachioradialis and brachialis.

The EZ bar curl offers a slightly supinated grip that reduces wrist strain compared to a straight bar while keeping significant biceps involvement. Hammer curls with a neutral grip target the brachioradialis and brachialis for a more complete elbow flexor stimulus. Preacher curls brace the arm against a pad to eliminate body momentum, keeping tension on the biceps throughout the full range of motion.

Most importantly, this routine prioritizes stimulus and fatigue management, ensuring you can recover for the next training session while removing unnecessary work and further limiting fatigue.

Warm-Up

To properly warm up for this routine, you simply need to warm up the muscles around the shoulder, elbow, and wrist joints by moving them around with intent or doing some named mobility movements. Then, do some warm-up sets for the main exercise. For example:

Light Mobility Drill: Shoulder Circles -> Elbow Circles -> Wrist Circles for a round or two with enough reps for you to feel them working.

Warm-Up Set/s: You can either do an easier variation or modified version of your first exercise, or do your exercise with some reps far from failure.

Just make sure that whatever you do is just enough to work and warm up your muscles, not tire them, so you can perform your best in your working sets.

Exercise Selection
Choose exercises based on the grip and the elbow flexor you want to bias. The table below outlines each category with its target movement, muscle, and example exercises:
CategoryGripTargetExamples
Biceps-biasedSupinated / Semi-supinatedBiceps Brachii, Brachialis
Brachioradialis-biasedNeutral / PronatedBrachioradialis, Brachialis
Exercise Order

Place the supinated curl first if biceps brachii development is the priority. Neutral or pronated grip exercises can follow as secondary work for the brachioradialis and brachialis. If you want a peak contraction focus, preacher curls are effective early in the session before fatigue reduces control.

That said, these are guidelines — your needs and preferences always take priority.

Sets

The template recommends 2 to 4 sets per primary exercise. Leaning toward the higher end — 3 to 4 sets — tends to be more beneficial if you are relatively new to training. Research shows that less-trained individuals voluntarily activate a smaller percentage of their available motor unit pool — even at maximal effort — leaving more motor units unstimulated per set.

Additional sets provide more high-effort recruitment opportunities before fatigue accumulates and begins limiting motor unit recruitment. As neural efficiency improves with training, each set becomes more effective at reaching higher-threshold motor units, and 2 to 3 sets may be sufficient.

Proximity to Failure

While it is okay to go until failure — especially when you're new to training and haven't yet developed a feel for what near-failure actually is, making it useful to calibrate — it's generally recommended to use it sparingly and instead leave 1–2 repetitions in reserve (RIR).

This matters most when you have more exercises later in the session. Fatigue from going to failure on an earlier exercise carries over and reduces execution quality in the exercises that follow, reducing how effectively you can train them. Leaving 1–2 RIR on earlier exercises means you arrive at each subsequent one with more capacity. If you only have one exercise in the session, this concern does not apply and you can push closer to or until failure more freely.

Progression

Once you can consistently reach the upper end of the rep range across all sets with standardized technique and ROM, it's time to progress.

Add weight in small increments. The right amount scales with your current strength level: the more weight you're already lifting, the larger the increment will naturally be appropriate. If a jump feels too large, add a rep or two at the current weight until the increase feels manageable. Keep track of your lifts so you know exactly what to beat next session.

Training Frequency

Depending on your recovery rate, you can perform this routine 2-3 times per week.
