Routine 2

Dumbbell Bench Press, 5 sets, comprising 2 light warm up sets of 10-12 reps, and 3 heavy sets of 6-10 reps
Incline Barbell Bench Press, 3 heavy sets of 6-10 reps
Flat Bench Flys, 3 medium heavy sets of 8-10 reps.

Remember to warm up properly by starting with two light warm up sets on the primary exercises. Warmed up muscles work more efficiently and also greatly reduces the danger of injury.

You will notice that each routine totals no more than 11 sets, including the warm ups, giving you 9 heavy sets. This will give you a short, sharp intense workout and prevent any possibility of over training

Short, sharp, intense routines together with good nutrition and adequate rest and recuperation will guarantee you build slabs of rock hard muscle and give you the best chance of building a powerful chest and awesome pecs.
