Your core is made up of many muscles, including the oblique. They are essential for basic movements. They are also important in controlling your posture and pelvic position. They will strengthen your whole core. Strong core strength is vital for sport performance and can help you lift heavier loads.
Another common exercise is the plank. This exercise works many core muscles in the body, including the abdominals. It can also be performed on all fours with the heels over the toes.
Static hold bicep curl. Static hold bicep curls are a great exercise to isolate your biceps. A pair of dumbbells, or a resistance band can be used. Static curls are best done with your lower arm parallel to floor. You should also use a broad shoulder stance. Static curls are a great way for strengthening your biceps if you're working out at a hotel gym.
