doing “soleus push-ups” (think: toes-down heel-up-&-down while seated) led to impressive positive shifts in metabolism.
The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
Soleus Pushups (a name the authors gave to non-weighted seated calf raises); “A potent physiological method to magnify & sustain soleus oxidative metabolism improves glucose & lipid regulation” = some pretty remarkable & outsized positive effects on glucose & lipid utilization.
Soleus push-ups may indeed be a powerful tool for improving metabolism.
This study had people continuously do soleus pushups and they looked at things like blood glucose utilization, they looked at metabolism and so on.
The point is that people who did these soleus pushups experienced dramatic improvements in blood sugar regulation and in metabolism despite the fact that the soleus is just 1% of the total musculature.
if you're simply trying to add a bit more fitness and metabolic health to your overall regimen, soleus pushups, at least to me, seem like a very low investment, simple, zero cost tool to improve your metabolic health.
seems to me that doing less would still be beneficial and that you don't necessarily have to do the full 270 minutes in order to get the benefits that they observed.
But there's a study that came out of University of Houston recently having people do, now, this is a long period of time. Four hours a day of, basically, a soleus pushup, which is basically a heel raise. A seated catchphrase with one foot not weighted. And then they looked at it a bunch of things about glucose metabolism and glucose clearance and insulin levels. And they didn't conclude that people burned a ton of calories, but what they concluded was that blood sugar regulation improved greatly.
