Adding weights to your workouts is fun and challenging. It can be something little or big

Versatility
When designing an at home gym, you want to get the most bang for your buck! This means looking into equipment that can be used in a variety of ways. Luckily, our bodies are great and there are a TON of workouts that can be done simply with our own body weight. However, maybe we want to step it up a notch, we're getting bored, we want to try something new, or make it a little more fun. There's no rule that says you have to have any of this, these are simply good ideas for what equipment you might want to invest in for your home.

Gym equipment always comes down to preference, purpose, and budget. You'll find most of the items by going to Sporting Goods --> Exercise & Fitness --> Gym, Workout & Yoga { Link Here}
The first items I'd go for would be a jump rope, yoga mat, and interval timer. These are inexpensive and instantly add intensity and variety to whatever workouts you do, body weight or otherwise.
From Gym, Workout & Yoga go to Fitness Equipment --> Jump Ropes { Link Here} this will obviously lead you to a wide range of jump rope options. Personal taste comes into play here, but I prefer speed ropes like the one pictured above. { Link Here}
Next up, yoga mats. From  Gym, Workout & Yoga go to Yoga & Pilates --> Mats { Link Here} to bring you to your options. Again with personal preference, I like my mats to be thick. Like the one pictured. { Link Here}
Interval timers can turn any workout into a HIIT workout! HIIT is High Intensity Interval Training. Also, interval timers are great for running and jump roping. GYMBOSS is known for their interval timers, and I like to stick with what works ;)

Weights & Other
Adding weights to your workouts is fun and challenging. It can be something little or big, start where you're at with what you have. Most of your weights & dumbbells will be found { here} Here are some ideas on types of equipment that can help add a challenge to your workouts.
Barbells
Pull Up Bars
Equalizers
Sandbags
Now, you always want to stretch! The yoga mats mentioned before is great for that; however, if you want to go the extra mile for your muscles I'd check out a foam roller.
