The lymph is then moved along the lymphatic vessel network by either intrinsic contractions of the lymphatic passages or by extrinsic compression of the lymphatic vessels via external tissue forces (e.g., the contractions of skeletal muscles)

It is surprisingly hard to find a figure for the amount of increase or a study. I say that because I know I have seen this info before and without digging for it. I have no idea why I recall it as easy to find in the past when it seems so hard to find now. But I did find this study:

Exercise increased the clearance rate three- to sixfold

Potentially also of interest:

It is trivially easy to search for "exercise moves lymph" and get a bunch of stuff, but probably not the kind of stuff people on HN want to see.
