Looking for water balloon-ing arm muscles?

Hello everyone!
I wanted to take a couple of minutes to put forth to my valued followers a question. I am very curious...about the words we see when we look at pretty much anything to do with working out.
Words like "rip", "tear", "shred", "blast", "explode"...I could go on. Why is the verbiage associated with being healthy also the verbiage we use when describing destroying something? You have to admit...it doesn't make the process sound very fun...not that it is I guess..but this makes it sound more like detonating a building..not spending an hour or so sweating it out in the gym.
I spent my hour on the treadmill today trying to think of the words I'd use instead of these...
"rip" should be replaced with "cleave". It sounds more violent but also makes me think of boobies. Thinking of boobies makes me giggle..giggling makes others smile. I think the world would be a better place if we all used "cleave" instead of "rip" moving forward.
"Shred" should be replaced not with a word...but with the sound the shredder makes when you put a piece of paper in there. It means the same...and the sound of the machine is much more satisfying then the word. I realize this might prove complicating for the people who make all of the media for the products toting the label "Shred This!" or "Shred That!". It might be difficult to phonetically get the message across...but this is America...I'm sure they could figure it out.
"Explode" could be replaced with "Water Balloon". All water balloons EVENTUALLY explode, water balloons are super fun..to throw, and be hit with (usually),again evoking either a giggle or a laugh by both parties.
I'm still working on "Blast" and "Tear". Thankfully I will have another hour to contemplate this tomorrow as I "Cleave" it up on the treadmill! :)

I was really NOT in to going this morning, I mean EVEN more so then I usually an not in to going. I woke up at 2am to let the dog out and was already talking myself out of it. My body HURTS and feels tired. When I got up I was toying with the idea of doing a little on the Wii fit and calling it a day..but I knew I'd regret it. Plus, when I mentioned my brilliant plan to my husband he said "SEE..your already talking yourself out of going" after a brief (but evidently WELL understood silence) he quickly added.."not that I'm one to talk"...
So, I went, and was very happy to text my hubby and let him know that I went.
I saw a new person there today. He had on a GREAT sweatshirt that looked like it came STRAIGHT out of 1980. It was awesome! I wanted to ask him where he got it...but he seemed to really be struggling to stay upright on the treadmill..so I didn't disturb him.
If you have a good replacement word for a current work out word, I'd love to hear it!
Have a great day all!
