Simple 5-Second hold may supercharge leg strength gains

First seen Jun 27, 2026 · Last updated Jul 01, 2026 · Updated 2 times

Summary

This study tested whether adding a 5-second hold at the end of each leg-extension exercise boosts thigh muscle strength more than doing the exercise without the hold. Forty-three healthy, sedentary adults did leg lifts 3 days a week for 8 weeks. Researchers measured their leg strength and thigh size before and after the program to see if the extra hold made a difference.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Isotonic knee-extension exercise with added isometric hold
What this could lead to
If it works, this could show that a simple tweak to leg exercises—adding a short hold—builds thigh strength faster, helping people get stronger in less time.
What could go wrong
This is a small, completed study in healthy, sedentary adults. Results may not apply to athletes or people with knee problems, and the strength gains might be modest.
