3. Medicine ball crunches

Start with feet on the floor at a 90-degree angle. Lean back onto tailbone and lift feet off the floor at 45 degrees. Hold a 4 kg medicine ball at your chest. With knees bent and toes pointed upwards, extend arms with the medicine ball while bringing the knees towards the chest. Keeping the abdominal muscles contracted, bring the medicine ball back to chest and extend the legs without letting your feet touch the ground. Stay in that position and preform a Russian twist with the medicine ball for weighted resistance. Twist core with medicine ball from side to side. Keep legs as steady as possible while twisting without touching the floor. Do this as one motion for one minute, rest for 30 seconds, repeat 3 times.
