Brett Starkowitz, master trainer and director of education at Ten Health & Fitness, thinks walking is low-intensity cardio.
It seldom affects muscular mass or tone. Finally, right? Nope, keep hunting for the greatest treadmills.
Walking builds slow-twitch muscle fibres, which are required for prolonged activity.
The legs'swell' after walking to take in nutrients and expel waste items like lactic acid, adds Starkowitz.
This may explain your swollen calves after a stroll in the park, but the effect won't stay long.
A 2018 research from Nagoya University found that muscle quality increased after 10 weeks of 30-minute walks.
