Tip 1: Always Perform a Warm Up
Warm ups are vital to ensuring you have a safe and effective workout, there are two types of warm ups, non specific general and specific purpose driven warm ups.
For best results combine both; the general warmup should help mobilise your joints, increase body temperature and turn on your nervous system for what is about to occur.
A combination of dynamic mobility movements such as dynamic hamstring leg swings , ankle knee drives, glute bridges and spinal mobility drills should be done.
Followed by a generic warm up of:
DB squat to press
DB alternate lunges
DB bent over row
Perform 10 reps of each 3x over with 5-10kg DB's
A specific warm up would be the first two exercises performed with 40-50% 1RM , depending on the weights you want to use this might take 2-3 warm up sets.
