A typical marathon strength routine focuses on building single-leg stability, strengthening the posterior chain, and improving tendon stiffness rather than adding muscle size.

To avoid injuries while strength training for a marathon, use proper form, start with manageable weights, and increase the load gradually.

A beginner marathon runner should start with bodyweight and light-resistance exercises like squats, glute bridges, and calf raises to build strength, movement control, and tissue durability.

A 16-week plan gives beginners more time to build strength and adapt before heavy training, while a 12-week plan works better for runners who already have a solid strength base.
