Last clue in the riddle of the week

Here are the final two clues in the pre-Christmas riddle, and the solution will be revealed later today. Daniel and Belinda have been the best/closest guessers so far. 

Day 1, Clue 1: who can guess why I've had to do exercises this month to strengthen my quad muscles?

Day 2, Clue 2: who can guess why I took a pair of old shoes and taped them to a laundry basket this month?

Day 3, Clue 3: who can guess why I took the old trainers off the laundry basket and super-glued them to a piece of carpet?

Day 3, Clue 4: I've had to wash the pillow case a couple of times this month… but who can guess why my specially shaped orthopaedic pillow was lying outside on the ground so often?

Day 4, Clue 5: who can guess why I've been stretching my hamstrings this month, sometimes also while balancing objects (such as the laundry basket or the Ikea footstool) on the soles of my feet?

Last chance to submit your solutions (here, by email or on FB) and the answer will be here on the blog by this evening.
