Reviewer's report:
Thank you for the opportunity to review this manuscript, I have no COI to
disclose. 
The authors present an interesting study assessing factors associated with
physical activity among mothers. The study is well-written and would be
interesting to the readers of BMC Women's Health. The main issue with the
study is that it is quite lengthy for no reason at some points. Few comments: 
Please change the title to something simpler.
"outside versus inside location" this is unclear in the abstract, please rephrase.
Please shorten the abstract slightly, some parts are unnecessary. 
The introduction is more than 2 pages long… Please shorten so that it fits in one
page. There is absolutely no need to go into that much details in the introduction.
The statistical analysis section contains a lot of measures. Please move those
parts to a different section describing your variables, so that the statistical
analysis section is more focused on stats. 
"200/285 participating mothers (70%)", 70% is the response rate I assume? If so
please write "response rate = 70%)".
"Strength and limitations", please remove strengths. No need to highlight the
strengths of the study separately. If you really want to mention those points, you
should mention them in the discussion, rather than a separate subset. This section
should focus only on the limitations. 
The conclusion is way too long, please shorten it in half.
Table 1: mean and ranges are presented. Any reason for that? I think it would
make more sense to present means with SD or median with range (or IQR which
would be even better)… I suggest having medians with IQR.
