To burn 3,500 calories you should look at a span of days or weeks — it won't happen in one day. If your total calorie expenditure is 2,000 per day and you eat 1,500 calories per day, you're burning 500 calories per day. Over seven days, that's 3,500 calories or one pound of fat. The reverse is true if you want to gain weight.
For example, if you weigh 190 lbs (86.18 kg) and you do Crossfit in 30 minutes, then the number of calories you burned while doing Crossfit in half hour is as follows: 86.18 x 5.6 x 0.0175 x 30 = 253.37 kcal. Follow this chart to easily calculate your calories burned while doing Crossfit and other exercises. MET.
