Hello everybody!
I'm brandnew to the forum and I hope that the more experienced among you can give me some advice!
I used to be quite sporty when I was younger (until jr. high/high school). The last few years I haven't done anything at all, though.
I'm 30 yrs., female, 1.74m, 59kg.
My goal(s):
I don't wanna lose weight (though 2-3kg would be nice).
My main goal is to become fit (again) for a better health condition. Currently I don't have any health problems, but I just feel it's time to start things again.
I also want to get my body into shape.
The reason for posting is that I'm not sure how I should plan my training.
Thus far I've started with some light cardio, mainly aerobic and step aerobic for 30 minutes around 3-4 times a week.
I also want to start running soon. 5K program at first.
My situation:
I live in Japan and I don't have a car, so I don't have access to any fitness center or the likes. Starting in May the temperatues will go up like crazy and soon it will be super humid and hot making any outdoor exercise impossible. There are also no lakes or swimming pools close by
So, I wanna do my workout at home.
I live in a small apartment with only one room (and we're talking about Japan here, so it's really tiny!!).
My equipment:
Aerobic stepper
jump rope (can't use it inside, no space)
Want to get soon:
heart rate monitor
1kg dumbbell x2
fitness mat
hula hoop
So, although I'm highly motivated, I get frustrated because I have no clue how I should go about my training.
I just wanna have fund and do something for my health, but after googling around for a whole week, my head hurts and I'm just totally confused.
So, I should do cardio AND strength training?
I shouldn't do them on the same day?
3-4x cardio and 2x strength training is okay?!
I'm all alone and actually I'm extremely worried that by doing something wrong I might harm my health more than anything else!

Can I always do the same cardio (aerobic / step aerobic) or should I try to do different things?!
Is strength training even possible with almost no equipment?
How can I work on my body flexibility?
I'm really very confused.
I hope you guys can give me some good advice.
Thanks a lot in advance!
