I'm almost insulted Andy wouldn't direct my attention over this way...
almost.
I can give you any and all advice you need. Tell me what you do, for how long, and how often and I'll give you any modifications necessary.
You're mixing up cardio, which is good. Make sure, and this is important, that you have good posture when doing all cardio....even on the stairs when you're getting tired...keep your arms lower on the handles, shoulders down and not forward.
This will improve core strength and posture, as well as burn more calories.
You want to be building muscle/gaining strength right now, so look for a rep range of 8 to 10 on all exercises. Stick to compound (multi-joint) motions like bench press, shoulder press, and especially squats or lunges.
There's little need to focus on smaller muscles with multiple sets at this point (biceps, triceps). One or two sets is fine, but only after 2 exercises of 3 sets on the larger muscles.
You should aim to lift for at least 30 minutes, and follow it with 20 to 30 minutes of cardio...with a 10 minute cool down of stretching.
Do that 3 times a week, with one or two more days of 30 to 40 minutes cardio, and you will be amazed with the results.
If you come to a point where progress seems to halt, your body has adapted to the routine....basically it's programmed to do the work, and requires less energy to perform it. Once you reach this point, a change in the routine is needed, and I'll be more than happy to help you out.
Keep me updated.
