Everyone is saying to lift weights. I just do cardio and love it. I love walking. I do love using the bike and treadmill, but now for 2 months all I have been doing is staying around 250 to 255 pounds (115.67 kg). Even after walking from my house in Brooklyn to midtown Manhattan now for a month, I only lost 2 pounds (0.91 kilogram). But I have no idea what weights to lift at Planet Fitness, or even what weight. YouTube is useless, just men and some women showing off their bodies on how they lost the weight, but not actually telling you what to do.
