Peer-reviewed study

Quick answer

What this study found

Ozaki et al. (2013, Clinical Interventions in Aging, PMID 23573066) reviewed whether walking can build leg muscle in older adults. Walking, jogging or intermittent running for over six months can increase leg muscle size in older adults, and daily moderate-intensity walking was linked to larger, stronger lower-body muscles. The evidence is limited to older adults.

Kris's practical takeaway

Here's what to do with it.

Walking can add some leg muscle when you are older or starting from low activity. It does not replace lifting: walk for health and fat loss, lift to build muscle.
