bodybuilders don't train for power because they just need to lift it not with any speed they just want to be ripped. power lifters lift with speed so do explosive workouts.

power is a measure of speed of muscle contraction redsox not of how much that muscle can lift. power and strength aren't the same you train differently for each because they are different things. for example someone with the strength to lift 200kg lifts it in say 2 seconds their power output would be 200 divided by 2 meaning that they have a power output of 100kg/sec. whereas someone who can also lift 200kg but has trained for power could say lift it in 0.5 secs giving them four times the power output. as you can see both are as strong as each other but the second athlete was four times more powerful
