Rowing machine (old style, this is used to practice latissimus dorsi);
Butterfly machine or chest pliers (the style seems to be very old, and it is only one-way chest pliers. The new ones are all middle ropes. Using the middle disc to lock the angle, you can not only clamp the chest, but also practice the deltoid posterior bundle. Pictures are rarely seen in the gym at present, this is a chest clamp)
Elliptical machine (used for jogging or walking, a bit like spacewalking) is not suitable for ordinary people, because its stress in several directions is smaller than that of outdoor running and treadmill, and it is suitable for the elderly and dieters, because its advantage is to reduce knee wear and ankle sprain. This model in the picture is also old, and the new rear axle is wrapped)
Sit bench press, commonly known as Bumblebee (chest press, this * * * has three modes with similar shape, namely bench press, shoulder press and downward oblique chest press. I think this angle should only be bench press).
Scientific name: It seems to be called the Big Bird Comprehensive Trainer, commonly known as the gantry (a semi-free muscle multifunctional trainer, which exercises many muscle groups, including the second and third brachial muscles, deltoid muscles, latissimus dorsi and so on). , and generally will consume some extra energy after training in the main muscle areas).
I don't use bench press accurately, but I'm used to it. It should be called a chest pusher. The code word is not easy, I hope it will be useful to you.
