Bench dips, is a great exercise for triceps for beginners, that can be done anywhere you want. You will need a piece of furniture that is stable to to the floor, and you can make the exercise home. You can make this exercise with your feet placed on the floor or with your feet placed on another bench for more challenging exercise.
So now, if you are ready to start the exercise, place your hands on the edge of the bench, while your legs should be fully extended like on picture 1. That will be your starting position.
Whenever you are ready, start lowering your body until your upper arm and forearm make slightly smaller then 90 degrees angle. While you are lowering, try to keep your elbows to your body as close as possible. When you get to that position where your arms get to 90 degrees angle, pause for a second, just like on picture 2.
When the pause is done, with your triceps, start pushing your body to its starting position. Repeat this exercise for like 3-4 series, with about 15 reps per one of the series. If its too easy, even for more challenging exercise, you can put some weight on your upper legs, so it gets harder to do it.
