Strategy and Tips from Sara Sigmundsdóttir

This is a longer workout. Even though the clean and jerks feel light and easy in the beginning, it is important to pace yourself.

It's all about the last three rounds of pistols and heavier weight - that's where you are going to "die" and you don't want your heart rate to be maxed at theta time. 

Aim to improve your speed in each round (negative splits).

Know your limit on the weight and pace yourself to what is heavy for you. 

Have a routine on when to chalk and take breaks. Think about how you want to break it up and pace yourself to keep your heart rate steady. Find your rhythm.

Remember to breathe. Find a spot and look at that spot the whole time, trying to stay relaxed during your movements. Stay focused on what you are doing and not thinking about whats next. 


Get started on the machines (row, bike, or skierg) for about 20 minutes to get your heart rate up and sweat going. It's important to get your joints loose and muscle warm. Alternate between machines. 

This workout calls for a lot if hip work, so once you are a little warm, stretch your hips out for at least 10 to 15 minutes to help you get down in that pistol position.  

Focus on where you are the most stiff (shoulders, hips, etc.) and work on getting those muscles nice and ready.

Then go through some short rounds to feel the transitions and movements. 

Remember to fuel your workout with a little sugar to have some gas in the tank.
