after an initial check up (as per what kater has said)
swimming is good, low impact. You can't target spot areas on your body, it's an all over thing. I'm not keen on machines so won't comment.
Free weights are good, a swiss ball in the mix is better! Also doing sit ups on a swiss ball means your coccyx (tailbone) won't be grinded to oblivion like it would on the ground (mainly due to poor form anyway). A swiss ball is good for your core anyway (which is something you always want to work and is...erm..a core part of tightening up your abdominal muscles anyway)
If you're a fan of the gym, it's definitely worth having a talk to someone who works in there to probably start you up with a training regime, or at the very least teach you proper form with weights and non-weight exercise.
(a mixture of aerobic and anaerobic exercise is paramount, plus healthy eating)
Pull it in 100 times a day (minimum) whenever you think about it ...... pull in, hold and feel that toning up! Also get a Slendertone belt to use every day. Do NOT starve - that will make no difference at all.
swiss balls are good kitten! I just feel like a tit using them because I can't balance properly.
hehe...i used to sit on one religiously, looked a right tit too, but
your body eventually masters the ability to stabilize itself. It's got
to be the most passive way of strengthening your core (provided you
keep good posture..or get a chair add-on thingy)
I've never understood the idea of electrocuting yourself fit? unless slendertone takes in consideration to "exercise" all the auxillery muscles that are used to balance/counter-balance natural body movements, it just looks like a tool that exhausts your abdomen muscles for no reason which could prove futile in the long run (over exercised abdomen muscles...oooo, what's going on with your back, ah yes, it's curving...)
Any physical exercise, be it free weights, body resistance, pole dancing, swimming etc. etc. I'd favour over a micro-electrocution unit... (unless it's a TENS unit, they're awesome)
is it down the centre of your stomach that is struggling to pull in? ive had three kids, eldest 11 youngest 2 and i found out i had whats called 'post partum' or 'diastasis recti' where the muscles BEHIND your '6 pack' seperate.
if its this, dont try sit ups or anything that is generally known to 'tone' your belly as it forms your stomach muscles into a circular ball shape on the front of you. if you think it might be this i can send you some links to websites with simple breathing exercises that help you retrain your stomach. (ive even had personal training to make sure i was getting the right info)
let me know xx
*edit, if you want to look it up yourself either look up post partum, diastasi rect or rectus abdomini*
