| First off, CONGRADULATION on maintaining and sustaining that fit lifestyle. I am glad that you are aware it is a lifestyle change to lose the weight and keep it off and not just a fad / yo-yo diet. Props to you.
Secondly, adding spice to your workout; have you tried wearing spandex? Just kidding. If you want to continue the cardio route but add some difficulty, try doing HITT (high intensive interval training) once or twice a week for 20-30 minutes to start. If you do it right, you will feel like you want to throw up afterward initially. Try outdoor stuff beside the gym to supplement your workout, like running around the lake / beach or hiking up a mountain or surfing or rollerblading, etc etc.. you know where this is going.
Thirdly, you admit to positive comments people give you that haven't seen you for awhile, then may I suggest doing weight training to add mass? Increase the workout weight training time but also crank up that intensity via increasing the weight and incorporating more sets / reps. Do a baseline of for one week and then each progressing week, add an extra rep or add another 5-10 lbs. If you are trying to gain some muslce, take some protein supplement and read the stickies. Set some goals that is difficult but achievable in 1 months time, 3-4 months time, and six month. Maybe work on the abs more and get that six-pack (not the beer, we have prankster who loves to say, I got a six pack... of beer that is). Once you pack on the muscle, watch people take notice and then you will get even more compliments and oggie eyes...
Good luck and Stay the path. keep it up.  |
