I will be 55 this year and have been working out with weights since I was 20 years old. I currently have all my equipment in my basement but it has taken a few years to assemble what I needed.
This is the type of leg press I have:
PowerLine Vertical Leg Press | FitnessZone
It works well and is about the cheapest you can buy. I am right at 6' and I think it would work for someone 6'3" One thing you could do as Forgeblast stated is work legs without a machine. One of the best exercises for legs is the lunge, standing one leg at a time or walking lunge. It will also get you heart to pumping.
This is one thing I am fairly knowledgeable on; fitness with weights. Don't forget to do cardio as the heart is the most important muscle you need to work.
Many times people think because they live in the rural countryside and work outside in the yard or garden that they are getting enough cardio and exercise. It is good exercise but you need at least 20 minutes of no stop cardio to get the best benefit.
Combining cardio and resistance training is the best way to get in shape, diet is also very important. Diet is a word that should not be used, I always say eating healthy; 40% protein, 30% good cards, 20 % fat at each meal. I usually eat 6 times a day spaced out from 7:00am to 9:00pm. Sometimes a meal or snack is an apple and a couple of peanut butter and whole wheat crackers (home made not pre packaged).
People at work always ask me what exercise they can do to lose weight or tone their arms, etc. They are always going on some crazy diet or something. I have got tired of telling them what to do and now just say unless you are ready to commit to a healthy lifestyle nothing I say is going to make a difference. They usually say they don't have time, but I always ask them how much time did you spend watching TV last night. The answer is usually 3-4 hours. You can set aside 30 minutes for exercise. It may extend your life or at least if you live to 85+ you may still be able to walk around and do everyday task.
I will get off the soap box now. I can offer more advise but I learned a long time ago don't offer unless asked.![]()
In my opinion, this is some of the best fitness advice that I've read in a long time. As near as I can tell, there is no one perfect workout or "diet" for everybody, because you have to discover what works for you. I think you've hit the nail on the head with the comments regarding eating right and cardio. I am far from an expert, but I think moderation in eating and exercise would go a long way in curing a lot of ills.
Today, I work with many different people, and many of them have different philosophies on exercise. There is a young man that is built like the incredible hulk, but we discovered when we were working out together that while he can bench press 400 lbs, he can't run across a gym floor without stopping to catch his breath. Likewise, there's a slender young lady that runs half-marathons but can't pick up a box of copier paper (no upper body strength). These folks are both "in shape" in accordance to their own fitness goals (one likes to pick up heavy things and one likes to run a long time), so that is good. But in my opinion, and my opinion only, I think they should both do a little more cross training to be a little more "well rounded".
We do a fitness class here at my work a few times a week (pretty simple stuff - we rotate DVDs like some of the Jillian Michaels ones, some Beachbody ones, etc). and it's really amazing (to me) how just doing 30 minutes of exercise 2 or 3 times per week can improve your overall well-being. I think exercise, combined with eating right, can be some of the best time you invest in yourself.
I'll pass the soap box to someone else.
Good luck and take care.
