I'm writing a first-person essay about rebounding (working out on a mini-trampoline) and I'm looking for credentialed fitness and rehab experts to provide commentary backed by research. I'd love to hear from exercise physiologists, certified personal trainers (CPT, CSCS), physical therapists (PT, DPT), and sports medicine or physical medicine physicians. Please answer any of the questions below that fit your expertise (you don't need to answer all of them). Short, specific responses are easier to quote: In plain terms, how would you describe rebounding, and what makes it different from other forms of cardio? What are the main physical benefits of rebounding (cardiovascular fitness, balance, coordination, low-impact on joints, etc.)? If you can point to specific research, please do. Who tends to be a good fit for rebounding, and are there people who should be cautious or avoid it? What's your best safety and getting-started advice for a beginner? How often and how long should someone start with, and what do beginners most commonly get wrong? To be quoted, please include your full name, credentials/title, where you practice or work, and a link to your professional bio page if you have one.
