Tips to increase energy and endurance?
I train 5 times/week, each time 2-3 hours. Tuesday I train for 4 hours. On top of that I do 6 hours of salsa dancing/week. And I'm a grad student.
On the days when I have both dancing and aikido (mon-wed), that puts up about 5h/each day of physical activity, on Tues it's 7 hours. I feel exhausted when I get home and couldn't do anything else. But I am not willing to sacrifice either aiki or salsa, it's part of my life.
I would like some tips to increase my energy level and endurance to better handle the week. It's tiring sometimes when the first 3 days of the weeks I can't even lift my feet in the morning.
