I'd recommend opposite of the lift more and lighter. That's exactly how you work either endurance or build mass.

If you want hard muscle, lift as heavy as you can, for low reps. You will gain only moderate mass, if any, unless you eat a lot more. But your muscles will become like iron. And your strength will go way up. It's myofibrillar vs. sarcoplasmic hypertrophy. Unlike the muscles that need to be "pumped up" to look big or properly shaped and not deflated, like you get from pumping high reps and lots of weights while looking in the mirror in the gym and thinking how awesome you are, muscle put on with heavy weight is much more dense muscle that looks more toned all the time.
