Planking, benefits?


That is fine I tend to do 30-40 minutes on a morning doing situps with a one arm raise holding a kettlebell, leg raises, press ups, russian twists, planking, kettlebell side bends, kettlebell squat press and kettlebell side swings. They're all really simple to do for beginners like myself.
that'll do me for a daily session.....right...Google russian twists etc..:D
