EMS shape care spa for bad knees and back, 10-min session: Xpa
Xpa is an EMS shape-care spa in Yeongtong, Suwon, Gyeonggi. A visitor in her 40s with back and knee issues that made intense workouts hard went through a careful consultation, then did a 10-minute treadmill EMS session and 20 minutes of spa care, noting calf soreness the next day like after hiking and less leg swelling in the afternoons. It's a manageable option even for people who've never been into exercise.
