The weighted plank adds external load to the standard plank, typically a plate placed on the lower back. This progresses the exercise when bodyweight becomes too easy, building greater anti-extension strength. The added load increases time under tension efficiency.
When to use it
Use for plank progression for optimal results.
Who it's for
Intermediate lifters looking to progress their training.
Set up in a forearm plank. Have a partner place a weight plate on your lower to mid back, or use a weight vest. Maintain a perfectly straight line from head to heels. Start with lighter loads and progress gradually.

Get into forearm plank position.
Have partner place weight plate on back.
Position weight on lower/mid back.
Maintain straight line from head to heels.
Hold for prescribed time.
Don't let hips sag for optimal results.
Progress from bodyweight plank.
Start with light weight.
Need a partner for placement.
Or use a weight vest.
Use weighted planks when you can easily hold a standard plank for 60+ seconds and want continued strength gains without longer holds. They work well for strength-focused core training and building resilience for heavy lifts.
Weight too heavy for optimal results.
Loading more weight than you can control on the Weighted Plank often creates compensations that shift work away from your Rectus abdominis. Reduce the load until each rep follows the intended path.
Hips sagging downward, indicating weak core engagement.
Losing hip position during the Weighted Plank changes the loading pattern and can reduce the intended work for your Rectus abdominis. Keep your hips aligned with the setup cues and move only through the range you can control.
Poor positioning for optimal results.
Isometric holds like the Weighted Plank build strength at specific joint angles. This mistake changes the angle and reduces how hard your Rectus abdominis has to work. Lock into position and hold it.
Intermediate lifters looking to progress their training.
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3-4 sets of 30-45 seconds. Rest 60s.
This is one example of how Weighted Plank could sit inside a complete workout. Your plan may use different movements after Ely checks your assessment.
