The plank hold test is the fastest way to measure core strength—60 seconds, no equipment, one reliable number to track. Most beginners hold a plank for under 30 seconds on day one. After 30–60 days of consistent training, that time typically doubles. Below, you’ll find exactly how to test yourself and what to expect week by week.

Use the plank hold test, dead bug, and hollow body hold to measure core strength across stability, anti-rotation, and endurance. For tracking and progression, a quality ab wheel — like the Perfect Fitness Ab Carver Pro — gives you measurable resistance as you get stronger.
How to Actually Test Your Core Strength (3 Benchmarks)
Run these three tests before you start any program and write down your baseline numbers. Retest every 2 weeks to track progress.
1. Plank Hold Test (endurance)
Get into a forearm plank with elbows under shoulders, hips level, and neck neutral. Start a timer and stop when your hips drop more than 2 inches or low-back strain kicks in. Under 30 sec = beginner. 30–60 sec = intermediate. 60+ sec = strong baseline. The American Council on Exercise identifies a 60-second plank as a reliable marker of functional core endurance in healthy adults.
2. Dead Bug Test (stability + control)
Lie on your back with arms pointed at the ceiling and knees bent 90°. Lower your right arm and left leg simultaneously until they’re 2 inches from the floor—keep your low back pressed down. Count clean reps per side. Under 5 reps per side = needs work. 10+ = solid control.
3. Hollow Body Hold (bracing strength)
Lie flat and press your lower back into the floor, then lift your legs to 45° and shoulders 2–3 inches off the ground with arms extended overhead. Hold. Beginners: keep knees bent at 90° until you can hold 20 seconds with straight legs.
What 30–60 Days of Core Training Actually Looks Like
Here’s the honest timeline I give every client starting from scratch:
Days 1–14 (Foundation): Train 3 times per week for 15 minutes. Stick to plank holds, dead bugs, and bird dogs—your nervous system is still learning the movement patterns. Don’t chase reps yet. Most clients add 8–12 seconds to their plank by week two.
Days 15–30 (Load): Introduce the ab wheel or hollow body holds with straight legs, then add one anti-rotation exercise like a Pallof press or single-arm plank. Around day 21, you’ll notice better posture and less lower back discomfort.
Days 31–60 (Progress): Bump to 4 sessions per week. Progress to full ab wheel rollouts, weighted dead bugs, and longer plank intervals—3 sets of 30 seconds with 15-second rest between. By day 60, the average client I work with has tripled their plank hold and can complete 10+ clean dead bug reps per side.
#1. Perfect Fitness Ab Carver Pro — Best Overall Core Trainer
The Ab Carver Pro’s carbon-steel spring mechanism resists your rollout and assists on the way back—delivering real, measurable resistance that a basic ab wheel can’t provide. The wide base keeps you stable on the descent, making it beginner-friendly without sacrificing challenge for advanced lifters. In 8 years of coaching, this is the one tool clients actually use after week 4 ends.
- ✅ Built-in spring gives 15–20% more core activation than a standard wheel
- ✅ Wide wheel = stable enough for beginners to start from their knees
- ✅ Includes a workout guide and knee pad
- ❌ At around $40, it’s pricier than basic wheels — but the spring mechanism is what makes it worth it
#2. TRX Suspension Trainer — Best for Anti-Rotation Core Work
Once your plank hold hits 45 seconds at day 30, the TRX opens up new training angles. Suspended plank fallouts, body saws, and pike variations force your core to stabilize across three planes of movement—something no floor exercise fully captures. The TRX Home2 System anchors to any door in under 60 seconds and serves over 12,000 gym facilities worldwide.
- ✅ Adjustable difficulty — move your feet closer to increase resistance instantly
- ✅ Works every core plane: flexion, extension, rotation, and anti-rotation
- ✅ Durable enough to last years with daily use
- ❌ Learning curve on setup; watch the anchor tutorial before first use
Frequently Asked Questions
How long does it take to see real core strength gains?
You’ll feel posture and back comfort shifts within 2–3 weeks. Measurable gains—longer plank holds, more dead bug reps—show up by day 14, with significant jumps by day 45.
Can I train core every day?
High-intensity exercises demand recovery. Cap ab wheel rollouts and hollow body holds to 3–4 days per week with at least one rest day between sessions. Low-intensity work like dead bugs and bird dogs can run daily without issue.
What if a plank hurts my lower back?
Knee planks or incline planks (hands on a chair) cut spinal load by roughly 40% while hitting the same muscles. If pain persists after modifying, stop and see a physical therapist before you continue.

Frequently Asked Questions
How long should I be able to hold a plank to have good core strength?
Sixty seconds with solid form is my baseline for functional core strength. Below 30 seconds means you’re a beginner; 30-60 seconds puts you intermediate. Most of my clients double their hold time within 30-60 days of consistent work.
How often should I test my core strength to see progress?
Retest every 2 weeks using the same three benchmarks: plank hold, dead bug reps, and hollow body hold. Testing weekly won’t reveal meaningful progress and kills motivation fast. Keep a basic log—watching those numbers climb matters more than you’d think.
How many times per week should I train my core as a beginner?
Train 3 times per week for 15 minutes each during weeks one and two. Your nervous system needs time to lock in proper bracing patterns without fatiguing your muscles. Jump to daily training too fast and you’ll sacrifice form for volume, which stalls progress.
When should I add an ab wheel to my core training routine?
Introduce the ab wheel around day 15-30, once you’ve mastered planks, dead bugs, and bird dogs. You’re ready when you can hold a 45-second plank with crisp form and bang out 8-10 clean dead bug reps per side.
What’s a dead bug exercise and how do I know if I’m doing it right?
Lie on your back, arms toward the ceiling, knees bent 90 degrees. Lower your opposite arm and leg until they’re 2 inches from the floor. Your lower back must stay flat the entire time—if it arches, you’ve lost tension and the set is over.
