Vinyasa yoga

Participants will follow a pre-recorded standardized sequence that includes a person demonstrating each sequence and provides verbal cues for the vinyasa yoga session. The 60-minute vinyasa yoga protocol incorporated standing, seated, and supine postures and included the following order of sequences: integration, sun salutations, crescent lunge series, balancing, standing, back bending, and restorative series.

BEHAVIORAL

Gentle yoga

Participants will follow a pre-recorded standardized sequence that includes a person demonstrating each sequence and provides verbal cues for the gentle yoga session. This sequence focuses primarily on seated and supine postures and is designed to be accessible, safe, and restorative. All poses are low-impact and supported using yoga blocks to promote comfort and reduce physical strain.
