Planks, but no planks

Have I mentioned that I hate planks? I do. I would have never attempted planking if it wasn't for the mysterious power an older sister has over you your whole life. But like with my most things my sister has convinced me to try, in the end I have to say thank you! I have complained and whined through planks most workouts for only a few short months now. Every time I would attempt to hold a plank for a thirty seconds or a minute, and each time after a few seconds into it I would fall down and hear that familiar voice from the fitness guru next to me say "get back up!". Oh I hated it! But something amazing happened. Yesterday I started my plank and I was able to hold it! What?? I still have so much work to do towards my fitness goals, how am I already holding a plank for a good thirty seconds? It's for a couple reasons. First, I have a trainer (sister/fitness guru) who pushes me try things and keep going even when it's hard or I don't think I can do it. She has me try things that not only would I not try myself, but that many people would think I couldn't do at my fitness level and weight. When I try these things and can at least do them a little bit, it is a triumph for both of us. Secondly, my body wants to change and grow stronger. A lot of times I would almost blame my body for my weight struggles but I have come to realize that my body doesn't like it any more than I do. It's just been waiting for me to do the work. This new found ability to plank doesn't mean that I can stop planking though, if I don't use it I will loose it. Now I just have to go take the confidence this has built and conquer some other goals. 5k? Push ups? A pull up???? I guess the sky is the limit.
