Introducing Soleus Health

MOVE WHILE YOU SIT.

Most health tracking focuses on sleep, exercise, and movement.
2HEART explores what happens in the lower body during the hours people spend sitting.
No electrical stimulation. No vibration. No motors. Just your own natural movement.
Device shown is a concept direction. Final design is under development and may vary. Currently in development. Prototype expected 2026.

The soleus muscle
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.

The Problem

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

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.

Devices built specifically for those hours
Every health device ever built was designed for the hours you are already active. Nobody built anything for the hours you are not.
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.

01
Place it beneath your desk
Designed to fit naturally under any standard desk. Non-invasive. Portable. No installation required.
02
Rest your feet on it while you work
Use it during work, reading, or any desk-based activity. No disruption to your routine.
03
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.
SHB — Soleus Heart Beat
A proprietary movement metric being developed to help users understand activity generated during seated sessions.

Device shown is a concept direction. Final design is under development and may vary.

Inspired by Published Research

Peer-reviewed research
from independent institutions.

2HEART did not conduct these studies. They are the work of independent researchers. Referenced to explain the science behind the soleus and seated physiology.

Glucose reduction*
In a laboratory setting using a specialised protocol, soleus activation during seated use reduced post-meal blood glucose excursion by up to 52% in research by Dr. Marc Hamilton.

We measure sleep. We measure exercise.
Maybe it's time to understand sitting too.

How many hours do you sit each day?

hours / day

What if you could change what happens during those hours without changing your routine?
