Arnold Schwarzenegger just dropped a workout that fuses CrossFit’s intensity with old-school bodybuilding, and it wrecked me—in the best way possible. Straight from his Pump Club newsletter, the “30-30 Dumbbell Challenge” is a time-based AMRAP-style routine designed to torch your muscles and flood your body with a skin-stretching pump. All you need is a timer and either your bodyweight or a pair of dumbbells.
Here’s how it works: set a timer for 30 seconds, perform as many reps as you can, then rest for 30 seconds before moving to the next move. It’s simple, scalable, and surprisingly savage. Two rounds take 10 minutes. Four rounds? You’re in Schwarzenegger territory.
At a Glance
- Goal: Pump, muscular endurance, cardio boost
- Time: 10–20 minutes
- Equipment: Dumbbells (optional)
- Format: 30s AMRAP / 30s rest, 2–4 rounds
- Benefits: Full-body burn, hypertrophy, functional stamina
Why the 30-30 Challenge Works
Timed sets force your body to push hard under fatigue. The 30-second AMRAP approach blends metabolic conditioning with hypertrophy training, making it ideal for fat loss, pump, and endurance. You’re not chasing reps—you’re chasing effort.
Schwarzenegger explains, “Timed sets let you get in a lot of reps fast. You’ll feel the burn, break a sweat, and walk away pumped.”

Bodyweight Version
Alternating Reverse Lunges
Builds single-leg strength and balance by working glutes, quads, and hamstrings.
How to do Alternating Reverse Lunges
- Stand tall, feet hip-width apart, core braced.
- Step back with your right foot until both knees form 90° angles.
- Keep your front knee over your ankle and chest upright.
- Press through the left heel to return to standing.
- Repeat on the opposite side without pausing.
Coach Tip: Keep your front shin vertical and gaze forward to protect your knee and maintain balance.
Push-Ups
A foundational upper-body move that targets chest, shoulders, triceps, and core.
How to do Push-Ups
- Start in a high-plank position with hands under shoulders.
- Engage core and glutes to form a straight line from head to heels.
- Bend elbows close to your body and lower your chest just above the floor.
- Pause briefly, then press through palms to extend arms fully.
- Avoid letting your hips sag or pike.
Coach Tip: If full push-ups are too tough, drop to your knees but keep a straight line from head to knees.
Pull-Ups / Inverted Rows / Supermans
Choose one based on available equipment to train back and scapular control.
How to do Each Variation
- Pull-Ups: Grip a bar slightly wider than shoulders, hang tall, then pull chest up while retracting shoulder blades. Lower with control.
- Inverted Rows: Set a bar at waist height, lie under it, grip with hands shoulder-width, pull your chest to the bar, keep body straight.
- Supermans: Lie face-down, arms extended forward, lift arms and legs simultaneously by squeezing mid-back and glutes, hold briefly, lower slowly.
Coach Tip: Prioritize scapular retraction—initiate the movement by pinching your shoulder blades before bending your elbows.
Air Squats
A core lower-body exercise that strengthens quads, glutes, and hamstrings while reinforcing squat mechanics.
How to do Air Squats
- Stand with feet slightly wider than hip-width, toes turned out gently.
- Sit hips back and down, keeping chest tall and spine neutral.
- Lower until thighs reach parallel or below.
- Drive through heels and mid-foot to stand.
- Reset briefly at the top before the next rep.
Coach Tip: Push your knees out along the line of your toes to engage glutes and protect the knees.
Mountain Climbers
A dynamic plank variation that elevates heart rate and trains core stability and hip drive.
How to do Mountain Climbers
- Begin in a high-plank position, shoulders stacked over wrists.
- Brace your core and draw right knee toward chest.
- Return the foot to start and immediately switch sides.
- Move quickly like pistons for cardio or slowly for strength focus.
- Keep hips level—avoid hiking or sagging.
Coach Tip: Keep your wrists directly under your shoulders and squeeze your glutes to prevent hip drop.
Dumbbell Version
Dumbbell Lunges
Adds load to lunges for increased strength and stability demands on quads and glutes.
How to do Dumbbell Lunges
- Hold a dumbbell in each hand at your sides.
- Step forward with right foot and lower until both knees are at 90°.
- Keep torso upright and core engaged.
- Press into the right heel to return to standing.
- Repeat on the left side, alternating each rep.
Coach Tip: Push through your front heel and keep your back heel off the ground to maximize glute activation.
Dumbbell Chest Press
Strengthens chest, shoulders, and triceps with controlled pressing under load.
How to do Dumbbell Chest Press
- Lie on a bench or the floor with a dumbbell in each hand at chest level.
- Plant feet firmly and press weights upward until arms are extended.
- Lower dumbbells slowly, feeling a stretch in the chest.
- Maintain a slight bend in elbows at lock-out.
- Keep your upper back glued to the bench or floor.
Coach Tip: Squeeze your shoulder blades together on the bench to create a stable pressing platform.
Dumbbell Bent-Over Row
Targets mid-back, lats, and rear delts while reinforcing hip hinge mechanics.
How to do Dumbbell Bent-Over Row
- Stand feet hip-width, hold dumbbells, hinge at hips until torso is nearly parallel to the floor.
- Let arms hang fully extended with a neutral spine.
- Pull dumbbells to your waist, leading with elbows and squeezing shoulder blades.
- Lower with control to full extension.
- Keep core braced and neck neutral.
Coach Tip: Don’t round your back—brace your core and hinge from the hips to protect your spine.
Dumbbell Front Squat
Places load at the shoulders to emphasize quads and core stability in the squat.
How to do Dumbbell Front Squat
- Rack dumbbells on your shoulders with palms facing each other.
- Stand feet shoulder-width and brace your core.
- Sit hips back and down, keeping elbows high so weights don’t pull you forward.
- Descend until thighs are parallel or lower.
- Drive through heels and keep chest upright to stand.
Coach Tip: Keep elbows pointed forward throughout to maintain an upright torso and protect your lower back.
Dumbbell Weighted Crunch
Intensifies core flexion by adding load to a standard crunch.
How to do Dumbbell Weighted Crunch
- Lie on your back, knees bent, feet flat.
- Hold one dumbbell across your chest or behind your head.
- Engage core and lift shoulders off the floor, pulling weight toward your hips.
- Pause at the top, then lower with control.
- Avoid pulling on your neck if weight is overhead.
Coach Tip: Exhale as you crunch up and focus on lifting with your abs, not your neck or shoulders.
Progression Tips
- Track your reps each round to beat your previous performance.
- Reduce rest time to 20 seconds for an advanced challenge.
- Alternate between bodyweight and dumbbell workouts weekly.
