see your medical provider for an "okay" before you start any exercise regime or diet program to make sure there are no medical contraindications. some overweight people find it better to loose some weight first before starting an aggressive exercise regime. exercise alone will not get those extra hundred pounds off.
i'm 54 and 100 lbs overweight. recently started zumba twice per week 7 wks ago & im feeling worse not better. about 20 minutes in the zumba routine i have trouble taking deep breaths i get a headache and emotionally i want to start crying. as i push myself through the hour routine my breathing and emotion gets better. i wonder if something may be wrong with me or if my big body is still trying to adjust. no hbp no diabetis only history of kidney stones and hypoglycemeia.
