So, 140lbs...
Pushups - vary your positions, arms spread, normal, close together, arms forward (more up by your head), and farther under your chest.
Or lifting makeshift weights - whatever you've got at home. Try and curl gallons of milk.
You can build up your triceps also by doing dips off a chair - sit on a chair, put your hands on the front edge of the seat by your thighs, scoot your bum forward off the seat, and lower your body down using your arms, then come back up.
