Can’t get up on a bike-don’t have the muscles for it

I have to do a fitness class in order to attend.

I have gotten into bike riding recently, but when I moved down south the first thing I wanted was a bike. I get to save on gas, stay in the sun as well as also be physically fit. I thought I would be so active as well as lose a bunch of weight due to biking. I got a speaker that hooks right to our handle bars. I have a holder for our phone so I can change songs when I want. I additionally clipped a water bottle holder to the front of our bike as well. I even fitted lights on the back as well as sides so I can ride at evening; After all this gear was put on, I realized that I suck at biking! My hands hurt from leaning so far forward on the bike. My butt aches by the end of an hour ride. I also have no strength in our legs at all to push. I don’t know I guess how to consistently change gears as well as handle a bike. I thought I would go into a gym as well as try stationary as well as stand up bikes. I could build the muscles as well as get to riding, and the only gym in our city is a core progression a single. This is a personal training center though. I have to do a fitness class in order to attend. I don’t guess if I want to do this. It seems sort of deranged to pay for a class to receive muscles in order to ride a bike. I could just keep on riding hoping I toughen up in our weak areas.
