Our coach shares a few exercises that you can do with your weights and a barbell
If you have a barbell and bench, then you can do bench presses.
This will work your pecs and triceps.
To gain strength, do 4 sets of 4 reps at 75% of your max. If you don't know your max, stop when you only have 2 reps left in you at the end of a set.
Over time, and as you get stronger, you can increase the load by adding 0.5 kg or 1 kg weights.
