Any tips please?

I've just completed week 4, run 1 and I'm loving this app. My problem is on the 5 min run I've found my legs are really heavy and feel like they can't go on even though the rest of me feels great. Would doing weights or maybe a rowing machine build up some strength?

I'm about 25lbs overweight and apart from swimming this is the first proper exercise I've done in 10 years.

Thanks in advance x

This is very normal as you get fitter and goes away very quickly. Make sure you are taking the two rest days and giving your muscles time to recover.
