Here is the link to my guide to weights that is full of links and some of my experiences and it may help. If you don't want to buy some dumbbells than there are weight bering exercies you can do sans weights - like
pushups. If you can't do many pushups on the ground a good way is too do incline pushups off of counter tops or walls, the lower the counter top the harder the pushup will be. Another pushup modification is to do them with you
knees in contact with the floor. Pushups work your chest (sexy firm muscle for your breasts to sit on and be perky), your shoulders, your triceps, and your biceps, abs, and thighs support you through the motion. They are a really great exercise for the whole body.
Tricep Dips: Are the exercise I see the most gains in the droopy tricep area, more than lifting weights. The link dip uses a machine but I use a bench or the edge of my couch (after I clear away the coffee table
sweatdrop ). You want you hands on a firm surface, fingers pointing out, stretch your legs out in front of you and lift and lower youself using your arms. The closer your legs are to your body the easier the motion.
T-stand: Although this is an ab exercise you do also use an arm to hold you up as well. If you're more advanced in the abs than in Denise modification you could put both your
legs out instead of moving one up like in the picture.
http://pilates.about.com/od/pilatesmat/ss/Plank.htm:Another exercise that works the abs but with assists from the arms. Lots of
plank linksSo I can't really think of non weight lifting excellent arm exercises buy pushups and dips but those are still going to give you results, lifting your own body weight is incredible.
My arm routine, every other day:
bicep curl x 10rep
shoulder press x 10 rep
tricep extension x 10rep
cycle through all three, 3 times (3 sets each) with a weight I can lift to temporary muscle fatigue in 10 reps
I also rock the tricep dip and counter pushups (counter pushups are a great "do I really need to eat or am I just bored?" Test)
If you're new to lifting weights starting out at 12 reps with a lower weight (that you can lift to temp. muscle fatigue in 12 reps) would be better than my 10. Learning good form is important.
Don't get caught up in what is "advanced" or not if it is challenging for you then that is awesome for you personally. Since you're asking I assume you aren't scared of getting giant arms which is very awesome because it just can't happen to us womens and our lack of high levels of manly testosterone. Unless we start drugging or work insanely hard to drop our body fat to 10% or so (I'm aiming for around 20 which is fit but no where near a body builder's body fat) we just aren't going to have the visual mass men can build.
Hope this helped and rock on!
