Generally speaking, low intensity workouts and stretching can be done every day without issue or even multiple times (consider a yoga instructor for example). Strengthening workouts can also be done every day when targeting different muscle groups (look up “split gym routine”).
The most important thing in all cases is working up to that level. Start small. Start simple. Look to exceed your capabilities and push for growth, sure, but limit that push to about 5% to avoid injury. To be clear: don’t push more than 5% past your last workout at any time. That includes your first few workouts 😉
You’ll get there!
Cardio exercise such as running, cycling and swimming.
