Locust (Salabhasana) is a back strengthening pose that will invigorate your practice and activate key muscles for more challenging poses like inversions.
Before you try Locust, practice Balancing Table Top to get an idea of the appropriate back activation without compressing the low back too much.
The goal is not bend your back in half!
Rather, this pose should feel supportive for your back.
Locust is an isometric hold that should strengthen the entire back of the body.
