I think I miscommunicated why I posted this comparison photo of a fitness model versus me:
I didn't mean to say that she looks 'better' than me, or that I'm trying to look like her. I was trying to convey the point that 'weight' is meaningless. She and I are both relatively the same height and weight, but our body compositions are very different. A lot of people set goals of weighing '140lbs by xx time'. Weight does not necessarily equate to fitness.
The reason why I've chosen a pull up as a fitness goal is because I need something challenging. If I don't have a goal post, then I tend to do nothing at all.
Why not a pull up? I'm learning that it is a very intense full body exercise that is an excellent marker of overall body strength. Many people overwork certain muscles and underwork others. Being unable to do a pushup OR a pullup is an indicator that one or more of these muscle series is weak.
Therefore, people who can do pushups and pullups have very well balanced overall strength.
I think that is good enough reason for me to do it. I reached my goal 6 months back of achieving college weight. Now I'm reaching higher. I want to be BETTER than I was in college. And I am defining what that means. I'm not competing against anyone else but myself. I'm the one that has to live in my own skin.
I'm not jumping straight into the weights because I've got some pretty weak deficiencies, and I'm risking injury if I push too hard too fast. Doing yoga and swimming might seem kinda odd if I'm trying for a pullup, but it's not if you think about it. Pushups/pullups are full body strength exercises. Yoga and swimming use almost every single muscle in your body. Thus, if you have muscle imbalance like I do where some are much stronger than others, than it is an easy way to transition the body to tighten those deficient muscles naturally. These are also activities that are enjoyable to me, so I'm more likely to do them. They will not be enough on their own to get to a pull-up. I'll add free weights once I feel that my overall muscle balance has improved.
For many years, I was 'fit-fat'. I was active hiking and biking, my favorite activities. Pushing around extra weight while making elevation gains of 3,000ft up mountains left me with a very strong lower body. (pressing 2x my body weight on the leg press), and a very neglected upper body.
My objective is to achieve overall wellness, not necessarily get a pullup the fastest that I can.
