Superset 4 – Pec Deck and Seated Chest Press:
At this point of your workout, weight and strength aren’t that important to you because the goal is now to keep ripping your muscle fibres. This means that you can now switch to machine exercises, which will help you isolate your muscles and develop them.
You can now use the pec deck since it’s a great exercise for this point in your workout. Concentrate on your chest instead of making sure you bring your hands together. When completed, approach a machine press, if possible one with a seat.
Doing horizontal presses will save your shoulders all the trouble of a vertical press, but make sure that your shoulder blades are squeezed together and your chest is stuck out as far as it will go. Do three supersets of 12 reps for each exercise here and you will see awesome results!
