A lot of friends/family ask me about weight loss solutions and I tell them that if they want to lose weight, they need to change their diet. If they want health benefits, they need to exercise, which may or may not lead to weight loss.
Hardcore exercise = increased hunger = potential overeating = potential weight gain.
Myself, I love lifting weights and doing yoga. I also enjoy that feeling of almost flying when sprinting or swinging my hips to a great beat. But also, from CW days, I always equated no exercise with weight gain/fat and this fear still stays with me. You have to find/stick with the things you love. I love my muscles and feeling strong, and, the serenity after a yoga session.
If you think the activities you do on a weekly basis is sufficient to gain some health benefit, I wouldn't worry about it. Ask yourself, does your heart rate go up a bit at times, are you using your muscles? Muscles are pretty important in your long-term health, so as long as you're using and maintaining them, you'll be great. If you feel you're not, maybe just increase the intensity of some of your workouts. Like, for one yoga session a week, do power yoga. Or learn some full-body exercises you could do at the playground, I'm thinking squats, pushups, chinups. Think of these as "warm-up" exercises before you can do whatever you want to do on the playground.
