Improving My Open Play

Question
Hi, I'll start off with stats. I'm a 5'8, 15 stone 15 year old.

My body build isn't as fat as that appears, I am a strong brutish player, but the problem is that my fitness really lets me down. Although part of the reason is that I play in an open age catergory with fitter and faster lads in their 20s.

The question I really wanted to ask was, if I took up jogging along with my base routine:

30 minutes on an excercise bike
20 minutes on rowing machine
3 reps of 10 chest presses
3 reps of 10 flies
5 reps of 10 squats
3 reps of 10 bicep curls
3 reps of 10 shoulder presses

I do that once a week, then on another day I change it slightly to include more aerobic activity

45 minutes on an excercise bike (interval training)
30 minutes on a rowing machine
3 reps of 20 chest presses (lower intensity than usual)
3 reps of 20 flies (lower intensity than usual)
5 reps of 20 squats (lower intensity than usual)
3 reps of 20 bicep curls (lower intensity than usual)
3 reps of 20 shoulder presses (lower intensity than usual)

Then on my 3rd training day, I incoperate much more strength training, with a routine that looks like this:

20 minutes on excercise bike (intense resistence)
10 minutes on rowing machine (intense resistence)
5 reps of 7 chest presses (higher intensity than usual)
5 reps of 7 flies (higher intensity than usual)
10 reps of 7 squats (higher intensity than usual)
5 reps of 7 bicep curls (higher intensity than usual)
5 reps of 7 shoulder presses (higher intensity than usual)

However, I feel that this doesn't give my fitness a boost, I still get as tired as quickly.

So, should I try taking up jogging?

Answer
High Rubin,

I would replace the bike cardio with running (not jogging) 30-40 minutes no more. Timed run. Look to run further during the run each time so mark your distance. Try to run outside with hills involved. Keep the weights. Alternate the 30-40 minute running with sprint training. 4 sets of 5 30 yard sprints after a warm up. Work up to 90% sprint starting at 50%. Throw in some high knee fast strides up a steep hill in the same set/rep style up as well.

I am not a true trainer but that is what I would do.

I would try to find a local trainer to help out. The bike and rowing should really be there for off season maintenance  or if you have injury.
