I work at a radio station where the programming director has been going to Crossfit for 4-6 months. He’s always talking about it: his 5am workouts, his eating, his friends at Xfit, I think it’s his raison d’etre. He also goes to church, has a wife and child, but he talks more about xfit than any other topic.
The real fitness debate here is high calorie burning and high intensity workouts versus more conventional workouts imo.
And a more specific debate for those overweight.
I can only give my experience here.
I’m a former paratrooper who can get crazy about my fitness at times, but I’ve slacked over the past 7 years and I am overweight.
Diving back in I did 7 weeks of double Tapout XT workouts with low carb calories restricted diet of about 1800 calories per day.
After 7 weeks, I lost a depressing 3 lbs with grueling workouts.
I read some fat burn research and decided to replace my 2 hours of high intensity workouts with
2 hours of Fat Burn heart rate between 116-127 on Ellipitical with same low carb diet.
I lost 9 lbs in 3 weeks.
If you are overweight, Fat burn range matters. Don’t believe the higher calorie burn camp. There is some Fitness politics involved in that debate, I can only tell you what I have experienced.
