The side plank is a great core exercise as it forces the lateral stabilisers of the body like the oblique’s and glutes to work hard to maintain stability and alignment through the body. When you swap sides it will also highlight any deficiencies or weaknesses that may be present from side to side. 

The Snatch is one of the Olympic Weight Lifting movements and is in my opinion the most technical single move that you can perform with a barbell. It is built on the foundations of the overhead squat and although it can be taught safely to beginners with the right instruction, I’ve marked this as an advanced exercise as you should have some level of strength and experience with resistance training before giving it a go.

The broad jump or standing long jump is an introductory plyometric exercise that can help improve explosive power. Although it is introductory plyometrics, I’ve categorised this as being advanced because you need to have some strong legs to control the landings for this one. You should already be very comfortable squatting and should be able to at least squat your own bodyweight before considering this as an explosive power exercise choice.
