This chest workout wrecked me! Still sore!

Yesterday was my chest day and my workout left me worn out for the rest of the day and sore as fuck this morning. Here's what I did: 

1. Dumbell Flyes: 5 x 10-15 (15's used for the first set , 25's for the rest of the sets)*I actually did 22 reps with the 15's as a warm up*
2. Incline Dumbell Press: 5 x 10-12 (20's for first set, 25's for the rest) *15 reps with the 20's for warm up*
3. Decline Press: 4 x 10-12 (25 pounds on each side for the first set, moved up to 35 for one set and then 40 pounds for the last two) *20 reps with the 25 pounds for warm up*
4. Bench Press flat with smiths machine: 5 x 10-12 (bar + twenty pounds, bar + 30 pounds) *just the bar for twenty reps to warm up*

Notes: 

• I don't really like doing decline press so sometimes I half ass it. I should have forced myself to do another set. I did one set of warm up and 3 working sets. I should do at least four working sets. I sometimes struggle to figure out how I should sit to make this press work best. Yesterday I sat with the handles at chest level and my shoulders back. It must have worked because the top part of my chest is sore as fuck!
• I was very motivated today after going to the Arnold Expo over the weekend. I met Dana Linn Bailey who is such an inspiration to me. 
• I'm starting to rely more on dumbells and barbells to train rather than machines. I like learning to control the weight in my hands. I feel like machines are much easier!! Easier = not enough of a challenge.
