5-minute 145 BPM circulation cadence metronome and focus timer. Activate your "Second Heart" while working, studying, or watching video streams. Sitting stationary for prolonged periods causes venous blood to pool in the lower legs. Second Heart delivers a rhythmic 145 BPM circulation cadence paired with a 25-minute focus cycle to keep blood moving via seated calf/soleus activation without disrupting your workflow. For even greater circulation, standing up for a gentle, slow jog-in-place to the 145 BPM beat works even better.
