If you can't grab a barbell, grab a kettlebell. Kettlebells are convenient, effective, and safe (with proper coaching and technique). Kettlebells can be great for traveling, vacation, and just a break from the strain of heavy weights. I still enjoy traditional lifts but rarely end a workout without using a kettlebell. They are great for warm ups (wall squats, halos, get ups) and they are great finishers (metabolic training). Do yourself a favor, find a specialist and and sign up.
