Sciatica: Man holding his lower back in pain during workout on a running track.

Reduce lower back pain and relieve upper body tension with this 90-second technique explained by physical therapists Bob Schrupp and Brad Heineck, collectively known as Bob and Brad.

Not just the makers of one of the best massage guns on the market, the duo are also renowned qualified PTs and claim this simple exercise can “fix low back pain in 90 seconds.” The technique has apparently been around since the 1950s from The Jones Institute and is known as “strain, counterstrain, or positional release.”
