Mountain climbers are directed towards building your core strength and increasing you overall fitness. The first few are easy but they get super hard in no time! Check out the video I made here.
Just keep pushing on when it gets hard.
No pain no gain :-)
Frog squats are brilliant for getting your heart rate up and your legs working. Make sure you're bending your legs considerably every time you're doing the move instead of just bending over to reach for the floor. Your back should stay flat throughout the exercise.
Find a video of me doing frog squats here.
