Time for poor man weights. Get an old tire and make a sled. Get some 5 gallon buckets and quic-krete and make heavy things for weighted carries. Go find big rocks and lift them. Fill a duffle bag with sand and do cleans and jerks. If you want to get big and strong, you'll have to put in effort. If you're willing to put in effort, you'll find a way to lift heavy stuff.
