Is exercise healthy?-YES! How long?- Ideally 1 hour daily.
But not everyone can do daily exercise for 1 hour, for various reasons.
So what’s the next best alternative?
Split up the exercise timings
You can do half hour walk in morning and half hour walk in evening.
Three 20-minute workout sessions throughout the day. Even a slow walk for 20 minutes after breakfast, lunch, and dinner (about half hour after meal) would be beneficial.
