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.

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.

The decline bench press may function as an adjunct to the flat bench press but not as a replacement for the flat bench press.
