5. Leg Press
This is one of the best exercises for your chord muscles and you do this using a diagonal sled-type leg press machine. Starting with a weight level that you’re comfortable with, lie back on the machine on your back. Put your feet on the extreme top left and right sides of the panel in front of you. Now slowly let the weighted panel come down by folding your knees and then push it back up. Always keep your knees slightly bent and don’t stretch them out straight. Similar to the others, do about 2 sets of 8-12 reps each.
