Describe how training programs would differ for the following: weight training, weightlifting, power lifting, and
bodybuilding

Weight training, weight lifting, power lifting, and bodybuilding are all similar because they share a common goal: to create a physical challenge and improve someone's health (either physically or mentally).

However, although they are similar and focus around body power, different training approaches can be used.  

Weight training: can include dieting, changing sleep schedule, and exercising consistently.

Weightlifting: using dumbells, weights, bars, etc, to achieve muscles in parts of the body such as arms or back

Powerlifting: Similar to weight lifting, just more extreme.

Body building: Creating a muscular and fit body, by weight/power lifting, eating healthy, and working out.
