5 main ways to change for more challenging workouts:
How hard are you pushing? Do you push yourself to the MAX
each workout? Do you only ever “go through the motions”—social exerciser?
Do you vary your intensity to get different results? Do you like to
take your time? Do you like to “get it done”?
How often do you work out? How often do you lift each body
part? How often do you do intervals? How often do you do other fitness
How long do you workout at a time? How long are your lifting sessions?
How long are your intervals? How much other time do you devote
to fitness activities?
What type of activities do you do? Do you cross train? Are you training
for a certain sport? What lifts do you do for each body part?
How many “rest” days do you take? How much time between
each lifting set/exercise do you do? How much time between hard intervals
do you “rest”? How much time do you “rest” each day? Do you purposely
take time to “de-stress”?
