Exercise After Stroke: How to Regain Strength, Balance, and Cardiovascular Health

In my years of experience as a clinical exercise physiologist, I have worked with hundreds of patients after they’ve had a stroke. One thing that consistently stands out is that while rehabilitation focuses heavily on regaining movement, which is absolutely essential, the exercise needed to build stamina, improve energy, and address cardiovascular risk factors is often left out.

Most stroke survivors receive excellent physiotherapy aimed at restoring function: walking, balance, and the ability to perform daily activities. But very few are provided with structured programs that challenge the cardiovascular system, improve endurance, or reduce the risk factors that contribute to another stroke.

Can I play Pickleball After a Heart Attack, Stent, or Bypass Surgery? Getting Back in the Game.

Pickleball has exploded in popularity over the past decade—especially among adults over 50. What started as a niche pastime is now the fastest-growing sport in North America. And it’s easy to see why. With smaller courts, lighter paddles, shorter matches, and a welcoming learning curve, pickleball offers a uniquely accessible way to stay active. But the real magic is its social and welcoming atmosphere.  Whether you’re rallying with friends, joining a local league, or simply chatting between games, pickleball creates connection—a powerful motivator for anyone recovering from a health scare.

That’s why so many people recovering from heart events—whether it’s a stent, bypass surgery, or a diagnosis of heart disease—ask the same question: “When can I play again?” They’re not just looking for exercise. They’re looking to return to something that feels joyful, familiar, and social.

Can I Run After a Heart Attack? A Week-by-Week Guide
