Gentle and accessible exercise interventions may provide measurable benefits for individuals with stable HF. A randomized controlled trial published in Heart and Lung evaluated the GEtting iNTo Light Exercise for Heart Failure (GENTLE-HF) study, a 6-month online yoga-based program involving 61 participants.

Compared with the education-only control group, the intervention group demonstrated significant improvements in upper-body strength (p = .004), lower-body strength (p = .002), and endurance (p = .003). Age influenced outcomes, as participants older than 65 years experienced greater gains in upper-body strength and endurance (p = .012 and p = .028, respectively). Exercise adherence was high at 84.4%, and higher QOL scores were associated with greater adherence (p = .039).

These findings indicate that online gentle exercise programs, such as yoga, can effectively enhance physical performance and engagement among patients with HF. The results highlight the potential of remote, scalable interventions to complement physical activity guidelines and improve outcomes in heart failure management.
