Concentration Press

Lie back and press a dumbbell up slowly and deliberately, the way you would a concentration curl -- the point isn't the load, it's giving your chest your full attention through every inch of the range. Lower with a long, controlled count rather than letting the weight drop, pause briefly at the bottom without relaxing, then press back up while actively thinking about squeezing your chest together rather than just straightening your arm. Avoid any bounce off the bottom or momentum from your shoulders. Keep the tempo slow enough that speed never does the work the muscle should be doing.
