The plank exercises are some of the best forms of exercises for increasing your core strength
Plank
1. Lie facing front down on a mat with your elbows, forearms and toes resting on the mat
2. Your elbows should be bent at 90 degrees and your body should be in a straight line from your head to your feet
3. Hold this position for as long as possible
Decline Plank
1. Adopt the same position as the plank but elevate your feet behind you on a bench
2. This will increase the weight your abs need to manage increasing the difficulty of the exercise
3. Try and hold this position for as long as possible
Decline Plank with alternate foot touch
1. Start in the same position as the standard plank, but with your legs elevated on a bench
2. Keep your body in a straight line still
3. Slowly lower your legs alternately off the bench and onto the floor
4. You should feel a strong tension in your core
Incline Plank
1. Again, start with the same position as the standard plank, but elevate your elbows higher up on a bench
2. This is a slightly easier variation of the plank, and so good for beginners
3. Try and hold for as long as you can and then rest
