Cardio inside AlterMe has never been about one “right” way to move. It’s about giving you options—so you can choose what fits your body, your energy, and your day.That’s why we focus on the SmartZone, which for many workouts aligns with Zone 2 cardio—a steady, sustainable intensity where your heart rate is elevated, but you’re still in control. Training in this zone has been shown to improve aerobic capacity, mitochondrial efficiency, and metabolic health, while placing less stress on the nervous system than higher-intensity efforts. In simple terms: it’s the intensity that builds long-term endurance and cardiovascular health without burning you out.

You can reach the SmartZone in many ways, and you can monitor it however you prefer—heart rate data, perceived exertion, or simply tuning into how your body feels. What matters most isn’t the format or the metric. It’s finding an intensity you can return to consistently.
Inside the app, you’ll now find five distinct cardio modalities, each offering a different pathway into the SmartZone:

- Combat Cardio — explosive, power-driven conditioning
- Circuit Cardio — continuous, interval-influenced training that builds endurance without HIIT-style spikes
- Dance Cardio — steady-state movement with cognitive and emotional engagement
- Mobility Cardio — flow-based sessions that elevate heart rate while improving range of motion
- Cardio Sculpt —  Shoes-off cardio rooted in rhythmic, continuous movement.
- Off-screen cardio — walking, jogging, cycling, or any movement you track on your own

## So what is Cardio Sculpt?

Cardio Sculpt is a home for shoes-off cardio—designed for sculpt-style sessions that combine continuous movement, strength, and core engagement to elevate your heart rate in a controlled, sustainable way. These workouts are low-impact and beginner-to-intermediate friendly, making them ideal for moderate-readiness days or anytime you want cardio that feels strong, grounded, and intentional.

What makes this category unique is that the identity of each class lives with the trainer.
Sorel approaches Cardio Sculpt through a Pilates lens, emphasizing stability, control, and muscular endurance. Nikki brings a yoga-inspired approach, blending sculpting sequences with breath, flow, and nervous system awareness. Different styles. Same goal. With multiple cardio modalities inside AlterMe, the takeaway is simple: There are many ways to get your heart rate up—and they all count.

Variety keeps movement engaging. Choice builds consistency. And consistency is what drives long-term results. Cardio Sculpt expands the system by giving you another smart, sustainable option—so you can keep moving forward in a way that works for your body.


Introducing our new modality, Cardio Sculpt. It's shoes-off cardio, blending continuous movement with strength and core work to elevate your heart rate in a way that feels controlled, rhythmic, and strong. Each session is shaped by the trainer’s expertise—drawing from Pilates, yoga, or dance—so no two classes feel the same, even though the goal stays consistent.
