It is worth noting that throughout the next 4 weeks, these are my preferences - not necessarily the generic fitness preferences.
Core:
#1 - Snake stretch
Stretch out your abdominals but be careful if you have a bad back as you have to compress the spine.
#2 - Side ab stretch
A dedicated stretch for your obliques.
#3 - Supine stretch
An easy yet effective stretch, push your limbs as hard as you possibly can!
#4 - World's greatest stretch
Aptly named exercise, this really is a fantastic movement for the whole body.
#5 - Inchworm
Another great mobility drill that warms up the whole body and builds strength as performed.
Be your best!
