How can soleus push-ups lower postprandial blood glucose?

Soleus push-ups have been shown to significantly lower postprandial (after meal) blood glucose levels. According to a study discussed by Andrew Huberman in the Huberman Lab, participants who performed these push-ups experienced a 52% reduction in blood glucose excursions and 60% less hyperinsulinemia after meals. This means they had lower spikes in blood sugar and insulin compared to those who did not engage in this exercise.

Here’s how it works:

1. Small Muscle Activation: The soleus muscle, which is targeted during these push-ups, comprises only about 1% of the total muscle mass but has a unique ability to enhance metabolic regulation. This small muscle helps facilitate better glucose utilization without requiring extensive energy expenditure itself.

2. Sustained Contraction: When performing soleus push-ups (lifting the heel while seated), this low-level activity can be sustained over long periods, potentially for several hours throughout the day. Participants in the study engaged in a total of 270 minutes of these push-ups, showing the cumulative effect on blood glucose regulation.

3. Long-Lasting Benefits: Remarkably, improvements in blood glucose levels were observed to persist for up to two hours after meals. This suggests that even though they involve minimal local energy use, the push-ups have significant systemic metabolic benefits.

4. Convenience and Practicality: This exercise can be integrated easily into daily routines, making it an effective way to counteract the effects of prolonged sitting or periods of immobility, such as during travel or while at work.

Engaging in these exercises can be a practical and efficient strategy for improving metabolic health and managing blood glucose levels 1 2.
