2. I try to remind myself that what my body can do is much more important than how my body looks. I did a half ironman at 7 months postpartum. Even though it was the slowest half ironman I have ever done, I still crossed the finish line which is more than the majority of the population can do. I also regularly run 15km+ trail runs. My body is performing the way a healthy, fit body should perform, even if it doesn't look like it on the outside.
I would suggest you find some sort of physical activity that you like to do. Forcing yourself to go to the gym is fine and dandy, but you aren't going to keep going if it isn't something you enjoy doing. Maybe the activity that you like isn't the one that is going to burn the most calories, but so long as you enjoy doing it you are going to stick with it in the long run and that is what matters and is going to allow you to see results. Then monitor your success based on your achievements rather than how much weight you lose. "
Love your whole post, but wanted to highlight the above. First, congrats on completing the half ironman! That's fantastic.
Second, I want to nod in agreement on focusing on what one's body is able to do, and monitoring success based on achievement rather than weight loss. I'm a huge proponent of strength training, not only for its aesthetic benefits (burns more calories than cardio and tones you up), but one's mental attitude shifts from focusing on how much calories am I burning to wow! look how much stronger I am! Before, I could only lift X amount of weights. Now I can lift X. I never thought I could do "real" pushups! Now I can do them like nothing And the everyday benefits are fantastic. Being able to carry even older/larger children with ease. No needing help carrying heavy items like bags or boxes. One feels so capable. It's a fantastic confidence booster.
Thirdly, I'm also a huge proponent of home workouts. If one loves the gym, of course, go! But I know too many people who join, and then always have an excuse not to go. But if one has an exercise mat, dumbells, etc at home, they can't say: "well, it`s rather cold out today..."
Fourthly, eons ago, i read somewhere: "Make exercise part of your daily life like brushing your teeth. Make it become so natural that you can't imagine not doing it." One of the best pieces of advice I listened to.
