My resting HR was always around 52-55, but it is more like 65 now, for the past few weeks.  I also am reaching my 85% HR target much quicker in my workouts.  Some bizarre dizzy/lightheaded spells lately too, which may or mat not even be related.  

My workouts are as follow:  2x/week heavy lifting.  I take 1 week off every 12 weeks.
                                         3x/week cardio on treadmill/bike/eliptical for 45-60 min in an aerobic zone (HR 155ish)

I'm 38 so a HR of 155 is nearing anaerobic, in theory, but I can easily hold a conversation at 155.  I don't start feeling "winded" til my HR gets to at least 163.  

So if I have overtrained how long should I rest and is it the weightlifting or running that did it?  Also if it was just the weightlifting that cause it, can I still run while I take a break from weights?

Try this and let me know how you like it!

The Peak 8 routine it will quickly raise your heart rate 8 times for very short bursts, with a cooling down period in between. Ideally you’ll be sprinting or cycling full throttle for 30 seconds with a 90 second cool down in between each outburst. 

This is the fastest way to lose fat and build muscle in the body. Peak 8 actually stimulates the growth hormone in the body. I encourage you to visit Dr Mercola’s site to learn more about Peak 8 fitness because I personally feel that it is one of the best ways to exercise, especially considering the speed at which you can lose fat and build muscle. 

I highly recommend you read this article and watch the videos on the page. It will give you all the information you need to know about Peak 8 – Flood Your Body With This “Youth Hormone” In Just 20 Minutes 

What you eat after Peak 8 training does matter 

It’s recommended that you do not eat sugar or carbohydrate for 2 hours after the Peak 8 exercise because these foods can impact the release of the growth hormone in the body.  The link is below 

Figure your heart rate by this formula 
The Karvonen Formula is a mathematical formula that helps you determine your target heart rate zone. The formula involves using your maximum heart rate (MHR) minus your age to come up with a target heart rate range (which is a percentage of your MHR). Staying within this range will help you work most effectively during your cardio workouts. 

an example of the Karvonen formula for a 23 year old person with a resting heart rate of 65 beats per minute (*to get your resting heart rate, take your pulse for one full minute when you first wake up in the morning or after you've resting for a while). This formula also includes an updated calculation of maximum heart rate (the previous formula was 220 - age, which has now been shown to be inaccurate): 

206.9 - (0.67 x 23 (age)) = 191 
191 - 65 (resting heart rate) = 126 
126 * 65% (low end of heart rate zone) OR 85% (high end) = 82 OR 107 
82 + 65 (resting heart rate) = 147 
107 + 65 (rhr) = 172 
The target heart rate zone for this person would be 147 to 172 

First thing in the morning before you get out of bed have a clock with a second hand and check your resting heart rate then figure your rate by the 
Karvonen Formula above.

You burn 30 percent more fat from doing cardio after a weights session as opposed to cardio on its own.
