Hey there, im 19 years old and weigh 185. My BF is right around 17%.My current lifting experience is fairly short, only around a year and im trying to put on solid mass. I have already had my diet crituqued in the dieting forum and im ready to gain some weight. I lift 5 times a week giving each muscle their own day. This was my exact workout today (chest day). Is this a good workout for my chest once a week? Please keep in mind that I went till failure on the last of each lift.
