A peer-reviewed review found static stretching produced statistically significant range-of-motion gains (p<0.05) superior to both ballistic and PNF protocols over the long term.

With the neural groundwork laid, Huberman turns to the practical taxonomy of stretching methods. Dynamic stretching uses controlled movement through a range of motion with limited momentum at end range; ballistic stretching adds deliberate momentum, especially at end range — sometimes a full swing of the limb. Both are distinguished from static stretching, which eliminates momentum entirely and holds the end position. Static stretching can be further divided into active (contracting opposing muscles to drive the position) and passive (relaxing into it), with named methods like the Anderson and Janda approaches. Finally, PNF — proprioceptive neuromuscular facilitation — uses the body's own positional awareness, often with straps, partners, or machines, to progressively push and then relax end range of motion. [1] — Andrew Huberman "Not all stretching is the same. Dynamic stretching uses controlled movement; ballistic adds momentum, especially at end range; static holds…" 12:43 After laying out this map, Huberman delivers the evidence-backed verdict: for lasting flexibility gains, static stretching (which he includes PNF within) is superior. The others have their uses, but if the goal is durable range-of-motion improvement, static holds are the protocol to prioritise.
Not all stretching is the same. Dynamic stretching uses controlled movement; ballistic adds momentum, especially at end range; static holds the end range without momentum; and PNF uses proprioceptive feedback, sometimes with straps or partners, to progressively push range of motion. For long-term flexibility, static — including PNF — is king.
A major review found that all stretching types improve range of motion over time, but static stretching produced statistically significant gains over ballistic and PNF. The minimum dose: at least 5 minutes of stretching per muscle group per week, best achieved through 3 sets of 30-second holds done 5 days a week. This is a short, low-time commitment with outsized returns.
