Been training 5x per week - 3 on, 1 off, 2 on, 1 off. On the juice I go so much harder but still need recovery days. I'm in the later half of my 40's though and have only been working out for 5 years. I have chronic shoulder issues and have had tendonitis in both elbows and have learned that its much better to take a couple days off per week rather than be down for months.. thats so depressing .
