I Battle JustMerk in an Arm Day AMRAP Competition The gym

The gym was buzzing with energy long before the first rep was counted. This wasn’t a normal arm day. This wasn’t about casual curls, mirror flexing, or chasing a pump. This was competition day. Today, I went head-to-head with JustMerk in a brutal Arm Day AMRAP (As Many Reps As Possible) challenge—a test of strength, endurance, pain tolerance, and pure mental grit.

No excuses. No shortcuts. Just iron, sweat, and willpower.

What Is an AMRAP Competition?

AMRAP stands for As Many Reps As Possible. In an AMRAP workout, the goal is simple but ruthless: perform as many quality repetitions as you can within a fixed time or set structure.

Unlike traditional workouts that focus on sets and reps, AMRAP pushes you to:

Train beyond comfort
Compete against fatigue
Maintain form under exhaustion
Dig deep mentally

For an arm day, AMRAP is especially brutal because biceps and triceps are smaller muscle groups that fatigue fast—but when pushed correctly, they grow fast too.

Why Arm Day AMRAP Is a Different Beast

Arms might look small compared to legs or back, but anyone who trains seriously knows arm pain hits differently. The burn comes quick, the pump is insane, and quitting feels tempting every second.

An arm day AMRAP tests:

Muscular endurance
Grip strength
Mind-muscle connection
Pain tolerance

Going against someone like JustMerk, known for his intensity and consistency, made it even more serious.

Pre-Battle Mindset: Locking In

Before the timer started, both of us knew this wasn’t friendly lifting anymore. This was competition.

Mental Preparation

No ego lifting
Perfect reps only
Push until failure—not comfort

The rule was simple: strict form only. Any cheat reps didn’t count. If your form broke, your rep didn’t exist.

The Arm Day AMRAP Workout Breakdown

The workout was structured to hit both biceps and triceps evenly, forcing complete arm exhaustion.

Workout Format

Each exercise: 2 minutes AMRAP
30 seconds rest between movements
Alternate between biceps and triceps
Total rounds: 6 exercises

Exercise 1: Barbell Curls (Biceps AMRAP)

We started heavy to shock the arms early.

Why Barbell Curls First?

Maximum biceps engagement
Allows heavier loading
Sets the tone for intensity

The Battle

The first 30 seconds felt easy. By 60 seconds, forearms were burning. By 90 seconds, the bar felt twice as heavy.

Every rep slowed. Every curl demanded focus.

Key Rule: No swinging. Full extension. Full squeeze.

This round alone separated mental strength from muscle strength.

Exercise 2: Skull Crushers (Triceps AMRAP)

Straight from curls to skull crushers—no mercy.

Why Skull Crushers Hurt So Bad

Extreme triceps stretch
Long head activation
High fatigue carryover

The triceps started shaking early. Lockouts became battles. Elbows screamed, but quitting wasn’t an option.

JustMerk kept a steady rhythm. I matched rep for rep.

Lesson: Control beats speed in AMRAP.

Exercise 3: Dumbbell Hammer Curls

By now, the pump was insane.

Benefits

Targets brachialis
Builds arm thickness
Improves grip strength

Hammer curls may look simple, but under fatigue they’re brutal. Grip began failing before biceps did.

Each rep felt like lifting concrete.

Exercise 4: Parallel Bar Dips (Bodyweight AMRAP)

Now things turned savage.

Why Dips Are a Game-Changer

Compound triceps movement
Chest and shoulders assist
Mental toughness required

Every dip burned deeper than the last. Halfway through, shoulders joined the pain party. But form stayed strict—full depth, full lockout.

This was one of the most decisive rounds of the competition.

Exercise 5: Cable Curls (Constant Tension AMRAP)

Cables don’t let you rest.

Why Cable Curls Late in the Workout

Constant tension
No momentum
Insane pump

The biceps were already swollen. The cables made them feel like they’d explode. Slow negatives became torture.

Arm Day Truth: The pump hurts more than the weight.

Exercise 6: Rope Pushdowns (Final Triceps Burnout)

This was the finisher. No saving energy now.

Why Rope Pushdowns to End

Full triceps contraction
Great for burnout
Safe under fatigue

Arms were numb. Triceps refused to lock out. Every rep became a negotiation with pain.

The last 30 seconds were pure willpower.

The Final Count: Who Won?

After the timer ended, both of us collapsed—arms pumped beyond belief, sweat everywhere, lungs on fire.

The final tally came down to a razor-thin margin.

JustMerk’s consistency gave him an edge in early rounds. My endurance helped close the gap in the final movements.

It wasn’t just about who won—it was about who refused to quit.

What This Competition Taught Me

1. Endurance Beats Ego

Heavy weights mean nothing if you gas out early.

2. Form Is King

Strict reps make AMRAP brutal—and effective.

3. Mental Strength Wins Battles

The arms quit before the mind does.

4. Competition Pushes Growth

Training alone is good. Training against someone is next level.

Final Thoughts

Battling JustMerk in an Arm Day AMRAP competition was more than a workout—it was a reminder of why we train. Not just for looks, but for discipline, resilience, and self-respect.

The weights don’t lie.
The clock doesn’t care.
And pain is temporary—but quitting lasts forever.

If you want bigger arms, stronger mindset, and next-level conditioning, step into competition—even if it’s just against yourself.
