Hi,
I have an exercise machine (a really nice one

) and I also have an Olympic weight set and a bench.
During winter break, I have swimming practice for 3 hours each day. I also want to lift weights on some of those days but if I do my free weights workout, I cannot swim during practice. I feel exhausted.
So I was wondering if before swimming practice (2 hours before) it is OK that I workout on the machine because after a machine workout, I do not feel as tired as I do after a free weights workout and I am still able to swim. I go as heavy as possible on the machine, but if I go as heavy as possible with free weights, I cannot complete swimming practice!
What are your thoughts on this?
Thanks
