What is the difference between interval training and strength training?

interval training is fast tough and very effective for calorie burning. That does high intensity exercises with short periods of rest.

strength training is am exercise that focuses on using resistance to build strength and lean muscles. you can take a bigger break in-between sets because you can lift more on the 2nd or 3rd set

if your boyfriend is cheating on you, my best advice to you is to dump him, he's only going to drag you down. and if you do, don't fret there's plenty better that know how to treat a person right. i mean honestly, the whole point of a romantic relationship is love, and if you love someone you aren't going to cheat on them. i do believe in second chances, but why would he cheat in the first place? i personally feel that if someone cheats, they ruin any chance they wanted/had with you. i wish you the best of luck with this, hang in there.
