Another day of planking
See how this will go after Ski walking / running with walking poles exercise on St Hans hills
We actually did only 10s regular planking, then running up the steepest part of the hill, repeated this 3 times. 
75s Regular, not a problem just some tiny little shaking of the legs
75s Reverse, not good for my calves after the Ski walking / running with walking poles exercise 
75s Left side, singing again to survive but less pain today
75s Right side, had to switch position once because the left elbow protested, also singing to survive
