Ease back in, do not rush
Start with lesser intensity and shorter duration workout plans for the first few days after recovering from an illness. Your body may require more rest days between workouts.

Diet and hydration are important
Boost your immunity by increasing your intake of vitamin C and make sure to complete your course of medications.

Try isometric exercises
Isometric exercises involve holding the body in a position with no muscle/joint movement. They build muscular strength and endurance and are popular rehabilitation exercises.
5
Listen to your body
Pay attention to how you feel when you start working out. If you find yourself exhausted or achy, take that extra rest day or cut back a bit on your exercise.
