Exercise and stress management

I am conducting a survey on how different forms of exercise affect stress levels, and I hope you will take the time to answer a handful of simple questions. The survey should take no more than a few minutes, and I greatly appreciate your time!
1.Which do you feel helps you most effectively to relieve stress, strength training or cardio?(Obligatoriskt)
2.How quickly do you notice your stress levels beginning to drop?
3.Do you notice the same results for long-term stress as you do for short-term stress?
4.What environment do you usually exercise in?(Obligatoriskt)
