Does stretching count as exercise?

Yes, it does. Stretching/ flexibility exercises are among the main types of exercise that people are encouraged to engage in ( 19 ). Note that if you want to use stretching exercises for weight loss or muscle strengthening, you must increase the intensity of these workouts. Yoga and Pilates are good examples you can try.

Why am I sore after stretching?

Stretching is an exercise that pushes your muscles past their usual limits, which causes microscopic tears in the muscle. This leads to soreness and you require rest to allow them to repair and recover.

Is it better to stretch every morning or night?

Either is a good option, so go with whichever option feels best for you. The point is to stretch, so whether you do it in the morning, at night, or several times during the day, it doesn’t really matter. Consistency and proper form are what matter the most.
