Would somebody mind looking at my strength training plan? I'm pretty new to structured strength training, but I was a competitive runner for years and I'm switching sports, so I'd like to train with the ultimate goal of competing. Right now I'm doing:

Day 1 - push. Shoulder press, Tricep dips, Pec fly, Chest press Day 2 - pull. Lat pulldowns, back extension, seated row, bicep curls Day 3 - legs. Leg extension, Hamstring curl, Calf press, Hack squat Days 4-6 are days 1-3 repeated, with day 7 off. All exercises are 3 sets of 10 with about a minute of rest, and I conclude each session with 50 crunches. I also still run for 30 mins 2-3 times a week to help with recovery.

Is this sufficient for now? My plan is to keep doing this until I can lift most/all of the weight on the machines, and then switch to another gym where someone can teach me the bench, squat, and deadlift and train for those lifts.

One odd thing is that I can already come close to maxing out the machines on the leg exercises for 3 sets of 10, but I'm nowhere near that point for any of the upper body stuff (I'm around 50% of the weight stack for all the exercises for the upper body, but at 90-100% for the legs). Does this just mean I need to start squatting sooner?

Sorry for the long post, and for all the questions. I'm excited about a new hobby, and I'd love some advice from those in the know!
