Difficulty & Intensity Guide

This comprehensive guide will help you find which series is right for you

Difficulty Levels

Difficulty refers to the level of skill and technique called for in a class.

Introductory

Introductory classes are designed for those who have never taken a yoga or fitness class before.

As a step below the beginner level, introductory classes move at a slow pace, take time to break down each pose and exercise, and are shorter in length to help you build endurance as you create a new movement routine. These classes are generally bodyweight only and contain modifications to help you feel safe and supported.

Difficulty—Beginner—Outlined Copy Created with Sketch.
Beginner

Beginner classes are geared toward those who have very little exposure to yoga or fitness.

These classes offer many modifications and detailed instructions on fundamental poses and exercises. Beginner classes are perfect for someone who is looking to start a regular yoga practice or fitness routine, though they’re also suitable for all levels to practice and brush up on the basics with alignment and form. You can also find mindfulness and wellness in this category.

Moderate

As the next step up from beginner classes, moderate classes include higher-level modifications and less detailed instruction than you would find in a beginner class.

Moderate classes are well-suited for those who have previous yoga and fitness experience and a basic understanding of poses, exercises, and class structure. This is an excellent choice if you’re trying to maintain consistency in your routine and increase your strength, skills, and flexibility with a class geared toward all levels.

Intermediate

Looking for a challenge? Intermediate classes tend to weave in more challenging poses and high-intensity exercises at a faster pace.

These classes will help build your strength, deepen your flexibility, and enhance your body awareness. For yoga classes, you can expect creative transitions, options for arm balances and inversions, and workout-inspired flows. For fitness classes, expect heavier weights, a higher sweat factor, and a quick pace that challenges your strength and cardio endurance.

Advanced

These classes offer the perfect opportunity to explore your potential beyond what you’ll find in typical all-levels studio classes.

Advanced classes are designed for those with a strong and consistent yoga and fitness routine. Expect advanced-level inversions, arm balances, and backbends; challenging peak pose variations; deep flexibility; strength work; and tricky transitions. You’ll find your edge while exploring a greater level of strength, control, and skill work.
