Hi Pink -
Good for you for starting to work out
When I first started going back to the gym, I was HORRIBLY out of shape. I almost got winded just walking in to the gym from the parking lot, that is how bad it was. I had no idea where to start so I asked one of the trainers that are there to help people. He asked me what I like to do most, and I looked around the gym and said I liked the bikes. (I figured I could sit down and exercise, so how bad could THAT me??) So he told me to hop on, then after 10 minutes, he came over and told me to go home.
Wait!!! I said. I am not done. 10 minutes??
Yep, he said, go home. And come back tomorrow. And do it again. And again and again.
His point was - at it was well taken by me - when people first start working out again, they go to extremes (sometimes) and get so sore they never want to go back. Or they skip a day thinking, well, I will go tomorrow, and never do. So by limiting the first couple of weeks, I was only marginally sore and felt inspired to go everyday.
It may work for you, maybe not. Six years later, I am at the gym daily.
And I also echo the hot tub or sauna, AND lots of water. That will go a long way towards the aches and pains.
Good luck and good for you!!
