I wanted to go swimming after work yesterday, but worked late again and had no desire to do so after the end of a long day. Instead I spent a half hour doing some gymnastics and weight training, including:
100 push-ups
100 sit-ups
20 pull-ups (jump)
40 squats (body weight)
bench press
shoulder press
two arm row (I think it’s called)
etc.
Tonight I am hoping to get off work at a reasonable time so I can run with my running club tonight – if not it will be another run by flashlight.
Might be time for you to order one of the nifty headlamps from REI. I generally run on well-lit streets, but when I don't I use a headlamp. Works out well!
