First seen Jun 27, 2026 · Last updated Jul 21, 2026 · Updated 2 times
Summary
This study compares two approaches to improve flexibility of the hamstrings and lower back: static stretching versus full range of motion strength training using the Romanian deadlift. Healthy adults will perform one of the two exercises once a week for six weeks. Flexibility is measured before and after the program to see which method works better.
