Hello Fit reddit folks,

I am 5'10 155lbs. I get aerobic exercise as I bike to my job as a Sever (3.5ish miles of biking 5-6 days a week and 7ish miles on my feet)

I would like to tone up quick and hard, GF is out of town for a few weeks and want to "Wow" her when she gets back.

I have no gym, not weights (well i have two little 5lbs for some reason )

how can I make a noticeable difference in that time?

I'm open an ready and motivated. (oh side note, f-upd knees so I cannot run or jog hard)

edit: no she didn't say anything about this, I want to make a change and I figure impressing her is a good motivator

Edit WOW so this is the most toxic reddit I have ever been in. thanks fella's!

Nothing like looking for some good push-up/sit up and such advise and get told to kill myself.
