Running for 5k and Strength TRaining?

CoraGregoryCPA

I've been "training" for a 5k (my first small race). My runs were really good. Until I got the idea to start "strength training" at the gym. I've been doing 1 strength training session a week. I increase the weights weekly, but my legs feel heavier now than before and my runs are slower. Is this bad? Should I not "strength train" at all while trying to run for a 5k or any marathon for that matter? My legs feel sooo heavy . I'm confused.

Any help would be greatly appreciated! Thanks.

No, you should definitely strength train! Your legs may feel heavier d/t increased muscle mass, or just plain old fatigue (which you'll get used to and burn past). Keep it up, the strength training will increase your speed in the races!

Are you just working your legs? I do strength training and found that it helps me, but I only work upper body and core. I rarely do a leg workout other than my running, but I have heard that it should help you if you aren't going for the bulk. Less weight and more reps are what you want if you are training for a race.

Strength training is good for running. What might be happening is not getting enough nutrition after your workouts. When I upped my training I got "heavy legs" until I started eating more. It's just a thought....

When I do my strength training I'm doing legs and arms and abs.

I think it would be good if I lost some lbs in the process. I'm hoping that will help me on race day too. So, I try not to eat all of my calories back.

Oh the confusion.. But I'll keep "strength training". Is 1 day a week ok? And I shouldn't increase the weights weekly? Should I stay at the same amount of weights and just increase reps?

Thanks a lot!!

Every time you start a new routine or increase training instensity it is normal to have a decrease in performance until your body gets used to the new regime or the new distance or the new pace, etc, etc.

It is totally normal and within a month I'm sure you'll be seeing improvements.

Stick with it - I try to strength train (whole body) 2-3 times a week, and I found that it helped my 5K speeds a lot - your body is probably just adjusting to the new routine, or maybe you're going too heavy with the weights? Definitely keep it up - cross training also helps to prevent injury.
