If you are looking for some crazy high intensity/make you vomit type of workouts Crossfit may help satisfy your needs. This website has a workout of the day that is insane most days of the week. These type of high intensity circuits are great for fat loss and building muscle mass. I usually incorporate variations of these circuits with most of my cliental to bring about positive changes in their body composition. There are a few aspects about Crossfit that I do not agree with 100%, but if you are looking for a way to structure your workout so you feel sick after you complete it then you should check out this site.
Here’s an example of a Crossfit workout (it is today’s “workout of the day”):
Three rounds for time of:
24″ Box jump, 50 reps
185 pound Deadlift, 21 reps
30 Pull-ups
