Please choose the correct ending to complete the given sentence: Sports and Fitness: [header] How to do renegade rows [title] Choose the right dumbbells. [step] Because renegade rows are extremely challenging, and different from other exercises you may have done, start with a lighter weight and make sure you can do several repetitions with good form. [substeps] Generally it's best to start out with 5-or 10-pound dumbbells.

Ending1: After 12-15 repetitions, you'll increase to 30-100 repetitions with good form. You can do some one-arm riser (elbow bend) workouts as well. Ending2: Choose dumbbells with hexagon rather than round ends, so they'll be stable on the ground and won't roll around. If the exercise feels " easy " to you, go ahead and use a heavier dumbbell. Ending3: Generally speaking this amount of weight will help you improve. However, it won't be as much fun if you've been doing renegade rows and mastered them three-quarters of the time using heavy dumbbells. Ending4: For example, if you are doing free-weights, you might only try 5-or 10-pound dumbbells. If you feel yourself getting tired, and are having trouble maintaining your form, you can switch to a lighter weight.
