Upper body training

Reached 108 kg this morning but it doesn't really help me with anything except that I now have a large gut and it's harder to tie my shoelaces. Since flexibility and endurance are my forte I see no reason to continue this increase in body mass. I am not stronger nor am I "fuller" from the excessive amounts of carbs. 100 to 105 is my functional body weight if I am to preserve the aforementioned qualities.
