Try to see how many rounds you can do. Start with as little as 1 round. Do as many as you can. If you need more rest, extend your rest periods. As you get more confident, you can add more rounds and build up to 20- or even 30-minute training sessions. And, with TriadXP, it's easy to customize your workouts to fit your needs and situation.
If you want a training routine that is going to be easy to fit into your day, this is it. Many of us are out of shape because we lack the time and energy to work out. So, trying to start or maintain an exercise routine that takes 7 hours a week is just unrealistic. Instead, you can get an incredible workout 4 or 5 times a week in as little as ten minutes.
