Challenge yourself. How can it be boring if it's a competition? Your a guy, you like competition... we all do. Sometimes we wuss out on it because of fear of failure. Get a goal of big bench press or weighted pull ups with 80lbs around your back and go achieve it.
You can try kettle-bells as mentioned earlier or try lifting other heavy stuff like sandbags..read up a book Dinosaur Training by Brook Kubik and watch some footage on Youtube on lifting sandbags. Go boxing, or take up MMA if it's boring still.
