It is worth noting that throughout the next 4 weeks, these are my preferences - not necessarily the generic fitness preferences.
Bodyweight exercises:
#1 - Split squat
Still my favourite, bodyweight is a great way of doing this exercise.
#2 - Wall sit
Build strength by holding your position.
#3 - Lunge
Great alternative to the squat.
#4 - Single-legged glute bridge
Love this exercise! It is difficult to do but works great at activating the glutes.
#5 - Step up
Good for knee health and challenging without weights
Be your best!
