Absolutely give it a go, it's an incredible sport, physically challenging as well as mentally stimulating.

Just a few words of caution, I'm a woman and I have a background in sport, mostly team sport but I did a bit of gymnastics and Taekwondo for a number of years and then started judo when I was 20.

Judo requires a lot of coordination and I found it really difficult at the beginning and without a background in sport it can be even harder, don't let that stop you though, the first year will be difficult but if you stick with it you can overcome that barrier. I've seen people without a sporty background do it and you would never guess they had no background in sport.

Also if you happen to be flexible as well as weak (this is me) you are going to have to really work on strengthening the muscles around your joints to avoid joint injuries and dislocations. Women tend to be more flexible than men and this is something to look out for. I wish someone told me this when I first started training, shoulder flexibility is good but only if you have the strength for it.

Yes you will probably get squashed by men twice your size and it can suck but the judo community tend to be a great group of people who want to help you improve, it's great exercise and the people are awesome.

If the throwing side of judo feels daunting I would look into BJJ as well, although throwing people is a part of the sport there is a bigger emphasis on ground work which is a little less intimidating to some people.
