I've been doing my one-minute exercise routine for more than a year. I first started with one-min planking, now I've extended it to two minutes.
In addition, I've also included other one-minute routines such as squat, leg raise, dip, and dumbbell shoulder lift. The result is visible, I'm more toned than a year ago. Also, after I've cut carbo, I managed to bring my weight down to 70.2kg, weighed this morning. Sometimes, it crosses below the 70kg mark.
My bio data as follows as at today:
Height: 173 cm
Mass: 70.2 kg
Waist: 35.5 inches
Chest: 38 inches
Hope to reduce more mid section fats.
