What is the best type of stretching for men over 40 — static, dynamic, or PNF?

Proprioceptive neuromuscular facilitation (PNF) stretching (contract-relax technique) produces the largest single-session range of motion improvements (typically 10–15% greater than static stretching) by using reciprocal inhibition and post-isometric relaxation mechanisms, making it the most efficient flexibility technique for men over 40 who want maximum range of motion improvement per time invested, despite being more complex to perform correctly (Hindle et al., J Hum Kinet, 2012).

PNF basics: for a hamstring stretch, lie on your back, bring one leg to end-range (the stretch position), then contract the hamstring isometrically against your hand for 6 seconds, relax, and move into the new deeper range that the post-isometric relaxation allows. Repeat 3 times. The range improvement after a single PNF session is typically double that of static stretching held for the same time. For men who are time-constrained, PNF gives the most improvement per minute. The practical limitation: it is more technical and requires learning the technique correctly.

Honesty Scale: Solid (1) for PNF stretching producing superior range of motion gains compared to static stretching.

What to do: For the hip flexors and hamstrings specifically (the most clinically important tight areas in men who sit), learn the contract-relax PNF technique for these two muscle groups. 5 minutes of PNF for these two areas post-exercise 3 times per week is more effective than 15 minutes of static stretching for the same areas.
