It is worth noting that throughout the next 4 weeks, these are my preferences - not necessarily the generic fitness preferences.
Arm:
#1 - Overhead tricep stretch
This is great for increasing mobility for the upper body.
#2 - Seated bicep stretch
A stretch that benefits stretching the biceps and front deltoids.
#3 - Arm circles
A good mobility drill to get the arms warmed up.
#4 - Wrist extension
Everyone forgets about wrist health, they are essential for lifting weights and should be looked after.
#5 - Wrist flexion
Like #4, increase mobility by extension and flexion of the wrist.
Be your best!
