Would be better doing:
Monday - Gym
Tuesday - Gym
Wednesday - Rest
Thursday - Gym
Friday - Gym
Saturday - Rest
Sunday - Gym
With your routine you've got 4 days straight saturday to tuesday, whereas the one above it 3 days/2days/3days/2days. Of course it all depends on your commitments.
It would be harder to make a friday to the gym, but I'll see what I can do.
