More food, less cardio or more rest days

Hi,

Why do you think of this training program and meal plan?

Monday: Workout A on machines: Arm Curl (6x8), Lat pull (6x8), Dips (6x8), Lying Triceps (6x8), Shoulder press (6x8), Chin up (6x8), Cardio (20 minutes running)
Tuesday: moderate cardio (cycling 26 miles)
Wednesday: Free weights work out: Arm Curl (6x8), Tricep Extensions (6x8), Bench press (6x8), Crunch (6x30), Shoulder press (6x8), Lying Fly (6x8), Supine bicep curl (6x8), Squat (6x8)
Thursday: moderate cardio (cycling 26 miles)
Friday: Workout B on machines: Leg press (6x8), Leg Curls (6x8), Chest press (6x8), Chest fly (6x8), Arm Curl (6x8), Leg raise (6x8), Cardio (20 minutes running).
Saturday: rest day
Sunday: Workout A

And the following week I switch workout A with workout B. I am trying to do each set at my maximum (sometimes I only manage to do 3 reps).

As for the food, I am eating around 2300 kcal per day with diverse food: protein (eggs, tuna, chicken, yoghurt and nuts), carbs (bread, veg, yoghurt and nuts), fat (milk and nuts) and my treats (beer and chocolate).

I manage to maintain my weight with this program but I would like to gain a few more pounds. What do you think I should do: more food, less cardio or more rest days?

Thanks,
Jamal
