Does personal training or group exercise improve energy expenditure?

Does exercising with a trainer or in a group help increase energy expenditure? The answer is yes, activity based energy expenditure will increase the more you exercise and in In any way, this is very healthy for your heart and your vascular system, so I would definitely encourage people to exercise. However, I should also mention that the amount of calorie burn from exercising is quite low and a way of losing weight would definitely involve also controlling calorie intake through dieting as a primary means, but also supplementing it with calorie expenditure for exercising, But calorie intake is really the main way if you're interested in regulating weight.
