Pilates anyone?????

I was at my local exercise establishment a few days ago and ran into a friend of mine while working out. Let me preface this last statement by mentioning that it has been waaaaaaaaaay too long since I last worked out. I had to wipe the cob webs off of my tennis shoes and dig between the cushions of my couch to find my membership card. Yeah - it's been awhile. With that in mind, I was trying to get a "light" work out in so that I wouldn't completely overdo it and pay for my overzealousness with a week of aches and pains in places that I didn't even know could hurt. Back to my encounter with my friend. She is a work out fiend. She is about 5'6" and maybe, maybe 100 lbs. She works out religiously everyday! The invitation to join her for a workout was a mistake on my part. On this particular afternoon she was doing a body pumps class. Have any of you ever partaken in one of these classes??? In theory, they are good......but in reality they are not so good for me. I am not opposed to exercise at all as evidenced by my health club membership. What I decided is that I am opposed to these structured exercise classes that are run by energetic, buff, fat-free women that are a bit too enthusiastic for my taste. I can hear the voice still resonating in my ears...."And one more time....let's hold that for a six count.", "Feel the burn, ladies.", "Three more sets, you can do it...", "Here we go now.", "Keep pushing yourselves...". I glance up at the clock and realize that 5 minutes, yes that's right, I said 5 minutes have gone by. Are you kidding me????? This class is an hour long class, there is absolutely NO way that I am going to survive for another 55 minutes.......The whole time I watched the clock, vowing that I would NOT stop until the clock reached 5:30 p.m. The last part of the workout consisted of sit ups which I thought I could handle. WRONG!! My abs, or should I say flabs, were on FIRE!!!! Seriously....I asked the woman next to me where the fire extinguisher in the room was located because I was being overcome by the smell of burning flesh. The good news is that I survived to tell about it. I don't think that I will be returning to the class; however, because I don't do well in structured settings!
