I went to the gym last Thursday & Friday it was closed on Saturday and I also went on Sunday.

On those days I did:
45 bike level 8 - 9 random
30 - 45 treadmill incline 12 4mph
20 weights -15 pounds dumb b. & 30 - 40 bar b.
20 cross trainer/eliptical - level 8 or 9 - next week I will be reducing the level and staying on these machines for 30minutes

A lot of times I'm pressed for time, Most days I'm at the gym for 2 or more hours. My minimum is 1 1/2 hours yesterday I did only 45 bike, 30 tread m. & 15 cross t. I'm debating about going to the gym after work usually when I don't really want to go I'll push myself even if I go for only a hour or I'll do my exercises at home. Some exercise is better than none.
