What is Soleus Health?

Soleus Health is a wellness category introduced by 2HEART the practice of activating and tracking the soleus muscle for everyday body awareness during seated hours.

What is the SHB Soleus Heart Beat?

SHB stands for Soleus Heart Beat. It counts the number of soleus activations during a 2HEART session. A higher SHB means your second heart was active today.

How is 2HEART different from a fitness tracker?

Fitness trackers passively observe. 2HEART is designed around active soleus engagement and tracks activity during use through the 2HEART app.

Does 2HEART diagnose or treat anything?

No. 2HEART is a wellness and movement tracking tool. It is not intended to diagnose, treat, cure, or prevent any medical condition.

When will 2HEART be available?

2HEART is in development. First prototype expected 2026. Early access members will be first to know.

Who is building 2HEART?

2HEART is developed by Girsan Innovations Private Limited, New Delhi. DPIIT recognised, SISFS funded, IIT Mandi CSR grant winner, CDSCO registered, DST NIDHI Accelerator selected, incubated at SSIIE-TBI.

The Problem

For decades, we blamed sitting.
What if the real problem was what stopped moving while we sat?

When you sit for 8 hours, your second heart goes silent.
The calf pump slows. Circulation drops. Energy fades.

This is the blind spot in modern health.

Run 5 km

Go to the gym

Hit 10,000 steps

Wear a fitness tracker all day

AND

Still spend 10 hours sitting. Still experience the same circulatory slowdown.

THE PROBLEM WAS ALREADY BEING COVERED

Hindustan Times Indian Express Times of India ABP Live The Health Site

None of these articles mention 2HEART. The problem existed before we did.

The Second Heart

Your body has
a second heart.

The soleus is a muscle deep in your calf. Researchers sometimes call it the second heart because it helps move blood from the legs back toward the heart during low-intensity movement.

During prolonged sitting, it becomes largely inactive.

How It Works

2HEART keeps
it moving.

A wellness device designed to fit beneath your desk. Being developed with sensing and software capabilities intended to track activity during use.

Place it beneath your desk

Designed to fit naturally under any standard desk. Non-invasive. Portable. No installation required.

Rest your feet on it while you work

Use it during work, reading, or any desk-based activity. No disruption to your routine.

The app tracks your session

The 2HEART app is being developed to help you track activity during use and provide personalised insights through the SHB metric.
