I am a strength trainer. 20 years. Write to my 360 page so I can outline what works, and what does not, for you. Not enough space here.
4-6 days per week 30 minutes per day keep your heart rate (220-16= 204---------204-(.30 x 204)) at 140-150 bpm= so try the treadmill at 4.0 mph with a 2 % grade for 30 minutes. You need to eat 4-5 times per day. Eat high protein / low fat foods example: lowfat yoqurt, grapefruit, baked potatoe with no butter, and baked chicken breasts without skin. I am a CPT, HFI, CRT, RCP. Toning is low weight, high repititon. try push-ups, pull-ups. pilates, and yoga.
