I have not long started specifically trageting my core. Recently I have been doing the following after my conventional strength days, and the russian twists and plank after a boxing workout. Dumbell Deadlift twists 3x10 (5 per side) Supermans 3x as many as possible Chinnies 3x as many as possible Day 2 Turkish get ups 3x 10 (5 per arm) V sit ups 3x as many as possible Day 3 Russian Twists 3x8-10 Plank- held as long as possible Am I on the right track? should I be doing these at the end of my workouts? or at the start?
