Simple home exercises may help heart patients breathe and move better

This study tested whether a 12-week home exercise program could reduce a severe forward curve of the upper spine (hyperkyphosis) and improve physical ability and lung function in 62 heart patients undergoing cardiac rehabilitation. Participants were split into three groups: those doing the home exercises plus rehab, those doing rehab only, and those without hyperkyphosis doing rehab only. The goal was to see if adding posture-specific exercises leads to better outcomes.
