Why exercise if you go on hltv
You wont be able to do as many pushups so just do pushups first.
Why you asking this on hltv lol
Do your pushups and strength training first. Not only will you have more energy and therefore achieve a higher intensity but you also burn more fat overall. This is because of you most likely running on an empty stomach after your strength training, hence you burn fat instead of calories from the food you consumed before that.
you will not be able to run for 30 minutes unless you are experienced and in good shape. doing cardio beforehand will just tire you out.
Start with pushups and do Cardio at the end. Its better this way, maximum gainz
