The technique of dips may vary so that these muscles work more or less. Since the chest and triceps work in pairs - the more the chest is working, the less the triceps is used and vice versa.
In the initial position, your body is located vertically; your arms should be straight, elbows should turn back. After taking a breath, dip down as much as the flexibility of your shoulder joints allows.
Focus on the 90-degree angle in the elbows. During movement, the elbows are turned back and pressed against the body. While exhaling, dip up. If the exercise is difficult for you, unbend the elbows at the top point. This will give the triceps a short rest. If you are an experienced athlete, do not fully unbend your elbows. Strive to perform 10-15 repeats in 3-4 sets. Go down slowly, and get up quickly. As soon as all this is easy enough for you, start mastering push-ups on the bars with extra weight.
Recommendations: Do not bend the wrists; the grip must be tight and stable. The same goes for the shoulder joints. Do not use too wide bars (much wider than the shoulders). It makes the exercise more traumatic.
Try to keep the spine as straight as possible. The abs and back muscles help to stabilize the body. Before you begin to perform the exercise, be sure to warm up. Move slowly – it requires more effort and it is safer. You should keep all your movements under control. Do not try to exercise on too wide bars. The optimal distance between the crossbars is a little wider than your shoulders.
