text: when i workout at night the effect doesn't seem to stay the next day.? i work out at night, about 30 or so minutes before i go to bed. i lift weights, i do sit-ups, push ups to try to get myself back inshape from being slightly obese, im 5'11'' and weigh 187. after i workout i go and look at myself in the mirror and i think wow i look good, better than i did before. so i go to sleep and i wake back up and it seems, looks and feels like all the weight flab came back. any insight to this? your not suppose to work out at night, you're suppose to do it first thing in the morning (wake up extra early) you will feel the effects for the rest of the day and sleep better at night
