If your like me and cannot afford the iron at home, there are plenty of bodyweight movements you can perform for each muscle group. It won't do what weights will, but certainly will do a lot to help. Especially compared to nothing. Concentrate on getting a great contraction with each group.
Google whatever muscle group you are looking to workout. Tons of stuff has been posted since the shutdown. A few bucks on bands can help as well.
Get creative....my curls consisted of using the top of a clothing rack with 5 gallon buckets hanging from the sides. Just dont take a full month off of everything and you wont be so bad off.
