Are you meant to bring the bar all the way down to your chest on this excerise.
Also will doing 3 excerises before getting onto bench press affect my performance?? At home I usually do it first and do sets of 10 9 and 8. I was actually hoping no slightly increase weight in gym but I couldn't get on for awhile and when I did get on I could only do same weight but 8 6 5 :-(
I dont do decline bench. Why are you doing decline bench press?
but to answer your questions. yes bring the bar to your chest.
What kind of exercises are you doing first? You should have your biggest compound lifts done early in your routine.
I did Chest press, Cable crossover and machine fly's whilst I was waiting for them to get off the bench. I am going to try and get some 2.5kg weights from somewhere and keep doing chest at home I think.
I haven't done decline I was just watching someone in the gym do it but he wasn't bringing it to his chest and his range of motion didn't look big to me.
I do declines often. Mainly on days I don't feel like doing dips.
My reasons for incorporating declines are less strain on my shoulders and they are great for triceps (thus locking out) the movement.
I perform declines to both the nip level (works the Tris) and also a little higher up the chest. Just be careful and make sure you can control the weight.
Although they are not completely necessary, I enjoy throwing in a set or two of decline benching on chest workouts. Usually I do flat BB, Incline DB and Decline BB.
When I decline bench I bring the bar all the way down to nip level (maybe slightly lower.) As far as affecting your performance, the only negative you may have is tired muscles from early movements. Shouldn't be a problem as long as your doing heavy compounds before. I wouldn't start off with decline, just use it toward the end to finish off or as a variation to others.
I think it was more my tri ceps that kept giving in on me today on the bench rather than my chest.
