It will be a hard workout....If I hit legs hard with running the day before I lift the weight workout suffers big time..

Does your workout suffer for legs only, or for whatever you are training?

I guess I will take tommarow off and hold it off till saturday.

Just legs, eat some good carbs today, you probably burned a shitload of carbs playing tennis for two hours.

I know the day after I play paintball for hours, my legs are usually pretty sore and sluggish already... I haven't play tennis for a while... I used to, but I wasn't really weight training then... Just try it and see how it turns out

With paintballing, it was worse because it'd be pretty much an all day afair with little food, mostly a couple small snacks, so I'm sure that didn't help.
