I trained with weights regularly and religiously ages 26 to 67 or 68. Nowadays the weights have been replaced for the most part by elastic exercise bands. The first four years were in a health club but at age 30 when we got a large enough house, I set up a home gym that I still use today.

Recommend that you join a gym for the minimal time limit at first, to learn the basic lifts and techniques while simultaneously expanding your knowledge via the Internet to learn advanced concepts like pyramiding, time under tension, accommodated resistance, etc. some of which may interest you and prevent boredom and loss of motivation.

Sure, been pushing weight, generally 2-3 times a week, some weeks I'll fall off the wagon and not work out at all, then get right back on the workout schedule the following week. FEELING GOOD, strong, healthy, vibrant, energetic, is its own motivation. I can tell when I've spent too much time away from exercise. I start to feel BAD, weak, fat, bloated, lethargic, sluggish, lacking mental clarity, and I DON'T like to feel BAD.

Also, even when I miss a workout, I ALWAYS take a bike-ride, pretty much every day. I've heard that, while anaerobic exercise, weight training, is important to maintaing overall health, aerobic exercise, cardio is more important.

I have been lifting weights on and off for about 8 years, consistently for about 18 months. The most important advice I can give is that you be patient with yourself and consistently remind yourself why you started weight training in the first place.

The other thing that is really important is to find supportive people both inside and outside the gym. Happy Lifting!
