I have been following a routine where I warm-up to an exercise with smaller weights of the target weight (I maintain an Excel sheet to make sure I do at least as much as last time).
For squatting, I do:
- 7 x 60%
- 5 x 70%
- 4 x 80%
- 3 x 90%
Then 2 x 5-7 reps of 100%.
I just read a report that cardio may be better for warm-ups and full scale movement of the joints of the target muscle, eg. http://breakingmuscle.com/strength-conditioning/light-cardio-warm-up-best-before-strength-work
Could I replace these warm-up reps with simple few minute cardio exercises? (eg jumping, or no weight squatting etc)
