Tips & Warnings
Try challenging yourself by doing Russian sit ups holding a kettlebell or dumbbell in one hand as you perform the exercise. Hold the weight straight up over your body with your elbow locked as you sit up. Repeat for the same number of repetitions with the weight in your other hand.
Attempt another variation of the Russian sit up by keeping one leg straight and placing the opposite foot on that knee. Lift the straight leg approximately six inches off the ground and do sit ups with your hands behind your head. Repeat with an equal number of repetitions with the other leg straight.
Do not attempt to do a Russian sit up if you have any lower back pain. Stop the exercise if you experience any pain while doing this movement.
