"Back Extensions: A Key Exercise for Strengthening the Entire Posterior Chain and Supporting Back Injury Recovery"
Back extensions are often seen as basic exercises for the lower back, but Joshua Hash, founder of Strength Side, and mobility coach Ben Patrick, known as The Knees Over Toes Guy, believe they can significantly enhance overall body strength and resilience.
In a recent video on the Strength Side YouTube channel, Hash discussed how six months of regular back-extension training enabled him to recover from a long-standing back injury, improve his posture, and increase strength across his posterior chain.
“I came for the low back, but I got the whole posterior chain,” Hash stated.
**Importance of Extensions**
Hash explained that many adults spend a considerable amount of time sitting, leading to weakened hips, glutes, hamstrings, and lower back muscles. While many view back extensions as primarily targeting the lower back, he noted that the exercise engages much more.
“I thought of this as a low back exercise, and it is, yet the whole posterior chain gets to work,” Hash elaborated. He pointed out that extension is one of the first strength movements humans learn as infants when lifting their heads against gravity.
**Recovery from a Back Injury**
Hash's interest in back extensions started after he landed awkwardly during a backflip in early 2026, resulting in ongoing pain in his lower back. Initially, he hoped the discomfort would go away, but it persisted. Testing his strength on a back-extension machine revealed he was considerably weak in that area.
“Just 10 bodyweight reps was leaving me super fatigued and sore the next day,” he recalled.
This discovery motivated him to include back extensions in his routine twice a week.
**Results After Six Months**
The changes were remarkable. Hash progressed from barely completing 10 bodyweight repetitions to easily performing around 35 reps. He also added weighted variations and significantly enhanced his single-leg strength. One unexpected benefit was improved mobility.
“What I wasn’t expecting was my hips to feel more open,” Hash expressed.
He believes that strengthening the muscles on the back side of his body counteracted the effects of prolonged sitting and improved his movement quality overall.
“My back feels stronger, thicker even,” he said. “Fortunately, the back injury is a thing of the past.”
**Ben Patrick’s Guidance on Lower-Back Strength**
Patrick then provided advice on how nearly anyone can safely start back-extension training. He emphasized that understanding back pain requires a broader view, highlighting the importance of building overall physical capacity.
“This whole thing is a game of your demands in life versus your ability to handle them,” Patrick explained.
For those new to the exercise, he suggested starting with assisted back extensions and gradually increasing resistance and range of motion. As strength develops, athletes can move to weighted versions using plates, sandbags, or other equipment targeting their entire posterior chain.
**At-Home Alternatives**
For individuals without access to back-extension machines, Hash promoted an at-home variation shown by Patrick. By placing pillows against their thighs and pushing their feet into a wall, beginners can effectively activate their glutes, hamstrings, and lower back without needing special equipment.
Even brief holds of 10 to 20 seconds can provide a worthwhile training stimulus. After six months of practice, Hash concluded that back extensions are much more deserving of attention than they typically receive. What began as an effort to address a nagging injury ultimately became a vital part of his training, enhancing strength, posture, and comfortable movement.
