Leg Day at the Gym

Greetings again readers.  What are you doing to train?  

Today I'll share my leg workout.  Yes, I incorporate core work into leg day.

• 209 bodyweight squats using the Runtastic Squats app (4 sets total)
• 50 squats with a 10lb dumbbell in each hand (held upward much like a barbell) (3 sets total)
• 50 lunges (3 sets total)
• 60 side lunges (30 on each side; 3 sets)
• 60 Erect Lateral Bends (3 sets of 20)
• 2.5 minutes of planking
• 2.5 minutes of side planking (both front and side planning were broken up into continuous 30-35 second sets, where after a normal plank I would switch to side planking and so forth)
• 1 set of 10 leg presses
• 2 sets of 10 hamstring curls
• 3 sets of 10 box jumps (20") 

I finished off by swimming for 200 metres.  I should add that I would have done back extensions as well, but I saw the following sign on the Roman chair:

My objective today was to work on my core and leg muscles, obviously, in order to avoid common running injuries and increase my speed.  Incredibly I was also considering a 20k bike ride as well today, but I think I've done enough.
