Childhood Obesity Causes & Consequences. On this Page. Childhood obesity is a complex health issue. It occurs when a child is well above the normal or healthy weight for his or her age and height. The causes of excess weight gain in young people are similar to those in adults, including factors such as a person's behavior and genetics.
You're right, here's a quick calculation: Say you bench press a 100kg mass and it travels 1m (apparently you have really long arms). Lifting that weight 1m expends (100kg)(1m)(~10m/sÂ²) = 1000J. Converting to calories and then kilocalories (food calories), this gives you something one the order of 1kcal. Bench pressing 100kg burns about 1kcal.
Before you attempt a max bench press, lie to yourself about the weight. Say you have 200 pounds that you are about to try to bench. Lie to yourself and tell yourself that it is nothing and that you've done it before. Also, pretend that it is only 150 pounds for example.
