If you’re a weight fanatic, your probably going to spend some significant time with free weights. When you’re benching 260 pounds, do you want your girlfriend spotting you, or do you want a guy who can hold that weight by himself spotting you? Your girlfriend may get upset that you want to exclude her from your workout, adding extra stress to what is supposed to be a stress-relieving activity.
Men and women have different psychological approaches to motivating each other when it comes to exercise and physical activity. How many times you were called any number of derogatory names by coaches and trainers because they knew that their comments would motivate you to prove them wrong? Don’t try that with a woman. What you think of as “aggressive encouragement” may come across “being really mean” to her. Likewise, her “Great job, honey!” may not be what you need to hear in order to squeeze out a few extra reps.
